-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. -.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 , -.Xr cpp 1 , -.Xr make 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;
