lint

lint(1B)					     SunOS/BSD Compatibility Package Commands						  lint(1B)

NAME

       lint - C program verifier

SYNOPSIS

       /usr/ucb/lint [options]

DESCRIPTION

       /usr/ucb/lint  is  the  interface  to  the  BSD	Compatibility  Package	C  program  verifier.	It  is	a  script  that looks for the link
       /usr/ccs/bin/ucblint to the C program verifier. /usr/ccs/bin/ucblint is available only with the SPROcc package, whose default  location	is
       /opt/SUNWspro.  /usr/ucb/lint  is  identical to /usr/ccs/bin/ucblint, except that BSD headers are used and BSD  libraries are linked before
       base libraries.	The /opt/SUNWspro/man/man1/lint.1 man page is available only with the SPROcc package.

OPTIONS

       /usr/ucb/lint accepts the same options as /usr/ccs/bin/ucblint, with the following exceptions:

       -Idir	       Search dir for included files whose names do not begin with a slash (/) prior  to  searching  the  usual  directories.  The
		       directories for multiple -I options are searched in the order specified. The preprocessor first searches for #include files
		       in the directory containing sourcefile, and then in directories named with -I options (if any), then  /usr/ucbinclude,  and
		       finally, in /usr/include.

       -Ldir	       Add  dir  to  the  list	of  directories  searched  for	libraries  by  /usr/ccs/bin/ucblint.  This  option  is	passed	to
		       /usr/ccs/bin/ld. Directories specified with this option are searched before /usr/ucblib and /usr/lib.

       -Y P, dir       Change the default directory used for finding libraries.

EXIT STATUS

       The following exit values are returned:

       0	       Successful completion.

       >0	       An error occurred.

FILES

       /usr/lint/bin/ld        link editor

       /usr/lib/libc	       C library

       /usr/ucbinclude	       BSD Compatibility directory for header files

       /usr/ucblib	       BSD Compatibility directory for libraries

       /usr/ucblib/libucb      BSD Compatibility C library

       /usr/lib/libsocket      library containing socket routines

       /usr/lib/libnsl	       library containing network functions

       /usr/lib/libelf	       library containing routines to process ELF object files

       /usr/lib/libaio	       library containing asynchronous I/O routines
