lint

/usr/ccs/bin/lint [options] files

Detect bugs, portability problems, and other possible errors in the specified C programs. By default, lint uses definitions in the C library llib-lc.ln. If desired, output from .c files can be saved in "object files" having a .ln suffix. A second lint pass can be invoked on .ln files and libraries for further checking. lint also accepts the cc options -D, -I, and -U. It may accept additional cc options that are system-specific. See also Checking C Programs with lint, which is listed in the Bibliography. Note: this command checks programs written in ANSI C; use /usr/ucb/lint if you want to check programs written in pre-ANSI C. Note also that options -a, -b, -h, and -x have exactly the opposite meaning in the versions for BSD and System V.

Options

-a

Ignore long values assigned to variables that aren't long.

-b

Ignore break statements that cannot be reached.

-c

Don't execute the second pass of lint; save output from first pass in .ln files. (Same as BSD -i option.)

-F

Print files using full pathname, not just the filename.

-h

Don't test for bugs, bad style, or extraneous information.

-k

Reenable warnings that are normally suppressed by directive /* LINTED [message] */, and print the additional message (if specified).

-Ldir

Search for lint libraries in directory dir before searching standard directories.

-lx

Use library llib-lx.ln in addition to llib-lc.ln.

-m

Ignore extern declarations that could be static.

-n

Do not check for compatibility.

-o lib

Create a lint library named llib-l.lib.ln from the output of the first pass of lint.

-p

Check for portability to variants of C.

-Rfile

Place .ln output (from a .c file) in file, for use by cxref.

-s

Produce short (one-line) diagnostics.

-u

Ignore functions or external variables that are undefined or unused.

-v

Ignore unused arguments within functions; same as specifying the directive /* ARGSUSED */.

-V

Print product name and release on standard error.

-Wfile

Same as -R, except file is prepared for cflow.

-x

Ignore unused variables referred to by extern declarations.

-y

Same as using the directive /* LINTLIBRARY */, which is the same as supplying options -v and -x.
