-.Sh DESCRIPTION
-The
-.Nm
-utility attempts to detect features of the named C program files
-that are likely to be bugs, to be non-portable, or to be
-wasteful.
-It also performs stricter type checking than does
-the C compiler.
-The
-.Nm
-utility runs the C preprocessor as its first phase, with the
-preprocessor symbol
-.Dq Dv lint
-defined to allow certain questionable code to be altered
-or skipped by
-.Nm .
-Therefore, this symbol should be thought of as a reserved
-word for all code that is to be checked by
-.Nm .
-.Pp
-Among the possible problems that are currently noted are
-unreachable statements, loops not entered at the top,
-variables declared and not used, and logical expressions
-with constant values.
-Function calls are checked for
-inconsistencies, such as calls to functions that return
-values in some places and not in others, functions called
-with varying numbers of arguments, function calls that
-pass arguments of a type other than the type the function
-expects to receive, functions whose values are not used,
-and calls to functions not returning values that use
-the non-existent return value of the function.
-.Pp
-Filename arguments ending with
-.Pa .c
-are taken to be C source files.
-Filename arguments with
-names ending with
-.Pa .ln
-are taken to be the result of an earlier invocation of
-.Nm ,
-with either the
-.Fl i , o ,
-or
-.Fl C
-option in effect.
-The
-.Pa .ln
-files are analogous to the
-.Pa .o
-(object) files produced by
-.Xr cc 1
-from
-.Pa .c
-files.
-The
-.Nm
-utility also accepts special libraries specified with the
-.Fl l
-option, which contain definitions of library routines and
-variables.
-.Pp
-The
-.Nm
-utility takes all the
-.Pa .c , .ln ,
-and
-.Pa llib-l Ns Ar library Ns Pa .ln
-(lint library) files and processes them in command-line order.
-By default,
-.Nm
-appends the standard C lint library
-.Pq Pa llib-lc.ln
-to the end of the list of files.
-When the
-.Fl i
-option is used, the
-.Pa .ln
-files are ignored.
-Also, when the
-.Fl o
-or
-.Fl i
-options are used, the
-.Pa llib-l Ns Ar library Ns Pa .ln
-files are ignored.
-When the
-.Fl i
-option is
-.Em omitted
-the second pass of
-.Nm
-checks this list of files for mutual compatibility.
-At this point,
-if a complaint stems not from a given source file, but from one of
-its included files, the source filename will be printed followed by
-a question mark.
-.Pp
-The special input file name
-.Dq Pa -
-causes
-.Nm
-to take input from standard input (until end of file) and process
-it as if it were a
-.Pa .c
-file.
-If the
-.Fl i
-flag is given and
-.Dq Pa -
-is named as one of the input files, the
-.Fl o
-flag must also be specified to provide an output file name.
-The options are as follows:
-.Bl -tag -width indent
-.It Fl a
-Report assignments of
-.Vt long
-values to variables that are not
-.Vt long .
-.It Fl aa
-Additional to
-.Fl a ,
-report
-.Em all
-assignments of integer values to other integer values which
-cause implicit narrowing conversion.
-.It Fl b
-Report
-.Ic break
-statements that cannot be reached.
-This is not the default
-because, unfortunately, most
-.Xr lex 1
-and many
-.Xr yacc 1
-outputs produce many such complaints.
-.It Fl c
-Complain about casts which have questionable portability.
-.It Fl e
-Complain about unusual operations on
-.Vt enum Ns -Types
-and combinations of
-.Vt enum Ns -
-and
-.Sy integer Ns -Types .
-.It Fl g
-Do not print warnings for some extensions of
-.Xr gcc 1
-to the C language.
-Currently these are nonconstant initializers in
-automatic aggregate initializations, arithmetic on pointer to void,
-trailing commas in
-.Vt enum
-declarations, C++ -style
-.Dq Li //
-comments,
-zero sized structures, subscripting of non-lvalue arrays, prototypes
-overriding old style function declarations and long long
-integer types.
-The
-.Fl g
-flag also turns on the keywords
-.Ic asm
-and
-.Ic inline
-(alternative keywords with leading underscores for both
-.Ic asm
-and
-.Ic inline
-are always available).
-.It Fl h
-Apply a number of heuristic tests to attempt to intuit
-bugs, improve style, and reduce waste.
-.It Fl i
-Produce a
-.Pa .ln
-file for every
-.Pa .c
-file on the command line.
-These
-.Pa .ln
-files are the product of
-.Nm Ns 's
-first pass only, and are not checked for compatibility
-between functions.
-.It Fl n
-Do not check compatibility against the standard library.
-.It Fl p
-Attempt to check portability of code to other dialects of C.
-.It Fl r
-In case of redeclarations report the position of the
-previous declaration.
-.It Fl s
-Strict ANSI C mode.
-Issue warnings and errors required by ANSI C.
-Also do not produce warnings for constructs which behave
-differently in traditional C and ANSI C.
-With the
-.Fl s
-flag,
-.Dv __STRICT_ANSI__
-is a predefined preprocessor macro.
-.It Fl S
-C9X mode. Currently not fully implemented.
-.It Fl t
-Traditional C mode.
-.Dv __STDC__
-is not predefined in this mode.
-Warnings are printed for constructs
-not allowed in traditional C.
-Warnings for constructs which behave
-differently in traditional C and ANSI C are suppressed.
-Preprocessor
-macros describing the machine type (e.g.,
-.Dv sun3 )
-and machine architecture (e.g.,
-.Dv m68k )
-are defined without leading and trailing underscores.
-The keywords
-.Ic const , volatile
-and
-.Ic signed
-are not available in traditional C mode (although the alternative
-keywords with leading underscores still are).
-.It Fl u
-Do not complain about functions and external variables used
-and not defined, or defined and not used (this is suitable
-for running
-.Nm
-on a subset of files comprising part of a larger program).
-.It Fl v
-Suppress complaints about unused arguments in functions.
-.It Fl x
-Report variables referred to by
-.Ic extern
-declarations, but never used.
-.It Fl z
-Do not complain about structures that are never defined
-(for example, using a structure pointer without knowing
-its contents).
-.It Fl B Ar path
-Path to use when looking for the
-.Pa lint1
-and
-.Pa lint2
-binaries.
-Defaults to
-.Pa /usr/libexec .
-.It Fl C Ar library
-Create a
-.Nm
-library with the name
-.Pa llib-l Ns Ar library Ns Pa .ln .
-This library is built from all
-.Pa .c
-and
-.Pa .ln
-input files.
-After all global definitions of functions and
-variables in these files are written to the newly created library,
-.Nm
-checks all input files, including libraries specified with the
-.Fl l
-option, for mutual compatibility.
-.It Fl D Ar name Ns Op = Ns Ar def
-Define
-.Ar name
-for
-.Xr cpp 1 ,
-as if by a
-.Ic #define
-directive.
-If no definition is given,
-.Ar name
-is defined as 1.
-.It Fl I Ar directory
-Add
-.Ar directory
-to the list of directories in which to search for include files.
-.It Fl d Ar directory
-Use
-.Ar directory
-instead of
-.Pa /usr/include
-as the default place to find include files.
-.It Fl l Ar library
-Include the lint library
-.Pa llib-l Ns Ar library Ns Pa .ln .
-.It Fl L Ar directory
-Search for lint libraries in
-.Ar directory
-and
-.Ar directory Ns Pa /lint
-before searching the standard place.
-.It Fl F
-Print pathnames of files.
-The
-.Nm
-utility normally prints the filename without the path.
-.It Fl H
-If a complaint stems from an included file
-.Nm
-prints the name of the included file instead of the source file name
-followed by a question mark.
-.It Fl MD
-Pass
-.Fl MD
-to
-.Xr cpp 1
-causing cpp to create files containing dependency information for
-each source file.
-.It Fl o Ar outputfile
-Name the output file
-.Ar outputfile .
-The output file produced is the input that is given to
-.Nm Ns 's
-second pass.
-The
-.Fl o
-option simply saves this file in the named output file.
-If the
-.Fl i
-option is also used the files are not checked for compatibility.
-To produce a
-.Pa llib-l Ns Ar library Ns Pa .ln
-without extraneous messages, use of the
-.Fl u
-option is suggested.
-The
-.Fl v
-option is useful if the source file(s) for the lint library
-are just external interfaces.
-.It Fl U Ar name
-Remove any initial definition of
-.Ar name
-for the preprocessor.
-.It Fl V
-Print the command lines constructed by the controller program to
-run the C preprocessor and
-.Nm Ns 's
-first and second pass.
-.It Fl w
-Treat warnings as errors.
-.It Fl X Ar id Ns Op , Ns Ar id ...
-Suppress error messages identified by the list of ids.
-A list of messages
-and ids can be found in
-.Xr lint 7 .
-.El
-.Ss Input Grammar
-.Nm Ns 's
-first pass reads standard C source files.
-The
-.Nm
-utility recognizes the following C comments as commands.
-.Bl -tag -width indent
-.It Li /* ARGSUSED Ns Ar n Li */
-Makes
-.Nm
-check only the first
-.Ar n
-arguments for usage; a missing
-.Ar n
-is taken to be 0 (this option acts like the
-.Fl v
-option for the next function).
-.It Li /* BITFIELDTYPE */
-Suppress error messages about illegal bitfield types if the type
-is an integer type, and suppress non-portable bitfield type warnings.
-.It Xo
-.Li /* CONSTCOND */
-or
-.Li /* CONSTANTCOND */
-or
-.Li /* CONSTANTCONDITION */
-.Xc
-suppress complaints about constant operands for the next expression.
-.It Xo
-.Li /* FALLTHRU */
-or
-.Li /* FALLTHROUGH */
-.Xc
-suppress complaints about fall through to a
-.Ic case
-or
-.Ic default
-labelled statement.
-This directive should be placed immediately
-preceding the label.
-.It Li /* LINTLIBRARY */
-At the beginning of a file, mark all functions and variables defined
-in this file as
-.Em used .
-Also shut off complaints about unused function arguments.
-.It Xo
-.Li /* LINTED Oo Ar comment Oc Li */
-or
-.Li /* NOSTRICT Oo Ar comment Oc Li */
-.Xc
-Suppresses any intra-file warning except those dealing with
-unused variables or functions.
-This directive should be placed
-on the line immediately preceding where the
-.Nm
-warning occurred.
-.It Li /* LONGLONG */
-Suppress complaints about use of long long integer types.
-.It Li /* NOTREACHED */
-At appropriate points, inhibit complaints about unreachable code.
-(This comment is typically placed just after calls to functions
-like
-.Xr exit 3 ) .
-.It Li /* PRINTFLIKE Ns Ar n Li */
-makes
-.Nm
-check the first
-.Pq Ar n Ns -1
-arguments as usual.
-The
-.Ar n Ns -th
-argument is interpreted as a
-.Xr printf 3
-format string that is used to check the remaining arguments.
-.It Li /* PROTOLIB Ns Ar n Li */
-causes
-.Nm
-to treat function declaration prototypes as function definitions
-if
-.Ar n
-is non-zero.
-This directive can only be used in conjunction with
-the
-.Li /* LINTLIBRARY */
-directive.
-If
-.Ar n
-is zero, function prototypes will be treated normally.
-.It Li /* SCANFLIKE Ns Ar n Li */
-makes
-.Nm
-check the first
-.Pq Ar n Ns -1
-arguments as usual.
-The
-.Ar n Ns -th
-argument is interpreted as a
-.Xr scanf 3
-format string that is used to check the remaining arguments.
-.It Li /* VARARGS Ns Ar n Li */
-Suppress the usual checking for variable numbers of arguments in
-the following function declaration.
-The data types of the first
-.Ar n
-arguments are checked; a missing
-.Ar n
-is taken to be 0.
-.El
-.Pp
-The behavior of the
-.Fl i
-and the
-.Fl o
-options allows for incremental use of
-.Nm
-on a set of C source files.
-Generally, one invokes
-.Nm
-once for each source file with the
-.Fl i
-option.
-Each of these invocations produces a
-.Pa .ln
-file that corresponds to the
-.Pa .c
-file, and prints all messages that are about just that
-source file.
-After all the source files have been separately
-run through
-.Nm ,
-it is invoked once more (without the
-.Fl i
-option), listing all the
-.Pa .ln
-files with the needed
-.Fl l Ar library
-options.
-This will print all the inter-file inconsistencies.
-This
-scheme works well with
-.Xr make 1 ;
-it allows
-.Xr make 1
-to be used to
-.Nm
-only the source files that have been modified since the last
-time the set of source files were
-.Nm Ns ed .
-.Sh ENVIRONMENT
-.Bl -tag -width LIBDIR
-.It Ev LIBDIR
-the directory where the lint libraries specified by the
-.Bk -words
-.Fl l Ar library
-.Ek
-option must exist.
-If this environment variable is undefined,
-then the default path
-.Pa /usr/libdata/lint
-will be used to search for the libraries.
-.It Ev TMPDIR
-usually the path for temporary files can be redefined by setting
-this environment variable.
-.It Ev CC
-Location of the C compiler program.
-Defaults to
-.Pa /usr/bin/cc .
-.El
-.Sh FILES
-.Bl -tag -width /usr/libdata/lint/llib-lc.ln -compact
-.It Pa /usr/libexec/lint Ns Bq Pa 12
-programs
-.It Pa /usr/libdata/lint/llib-l*.ln
-various prebuilt lint libraries
-.It Pa /tmp/lint*
-temporaries
-.El
-.Sh SEE ALSO
-.Xr cc 1 ,

-.Sh AUTHORS
-.An Jochen Pohl
-.Sh BUGS
-.Bl -item
-.It
-The routines
-.Xr exit 3 ,
-.Xr longjmp 3
-and other functions that do not return are not understood; this
-causes various incorrect diagnostics.
-.It
-Static functions which are used only before their first
-extern declaration are reported as unused.
-.It
-Libraries created by the
-.Fl o
-option will, when used in later
-.Nm
-runs, cause certain errors that were reported when the libraries
-were created to be reported again, and cause line numbers and file
-names from the original source used to create those libraries
-to be reported in error messages.
-For these reasons, it is recommended
-to use the
-.Fl C
-option to create lint libraries.
