ULIMIT(3)	       FreeBSD Library Functions Manual		     ULIMIT(3)

NAME
     ulimit -- get and set process limits

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <ulimit.h>

     long
     ulimit(int	cmd, ...);

DESCRIPTION
     The ulimit() function will	get and	set process limits.  Currently this is
     limited to	the maximum file size.	The cmd	argument is one	of the follow-
     ing:

     UL_GETFSIZE  will return the maximum file size in units of	512 blocks of
		  the current process.

     UL_SETFSIZE  will attempt to set the maximum file size of the current
		  process and its children with	the second argument expressed
		  as a long.

RETURN VALUES
     Upon successful completion, ulimit() returns the value requested; other-
     wise the value -1 is returned and the global variable errno is set	to
     indicate the error.

ERRORS
     The ulimit() function will	fail if:

     [EINVAL]		The command specified was invalid.

     [EPERM]		The limit specified to ulimit()	would have raised the
			maximum	limit value, and the caller is not the super-
			user.

SEE ALSO
     getrlimit(2)

STANDARDS
     The ulimit() function conforms to IEEE Std	1003.1-2001 (``POSIX.1'').

HISTORY
     The ulimit() function first appeared in FreeBSD 5.0.

BUGS
     The ulimit() function provides limited precision for setting and retriev-
     ing process limits.  If there is a	need for greater precision than	the
     type long provides, the getrlimit(2) and setrlimit(2) functions should be
     considered.
