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
     following:

     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; otherwise 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 retrieving 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.
