NAME
       ulimit - get and set user limits

SYNOPSIS
       #include <ulimit.h>

       long ulimit(int cmd, long newlimit);

DESCRIPTION
       Warning:	 This  routine is obsolete. The include file is no longer pro‐
       vided by glibc.	Use getrlimit(2), setrlimit(2) and sysconf(3) instead.
       For the shell command ulimit(), see bash(1).

       The  ulimit()  call will get or set some limit for the current process.
       The cmd argument can have one of the following values.

       UL_GETFSIZE

       UL_SETFSIZE
	      Set the limit on the size of a file.

       3      (Not  implemented	 for  Linux.)	Return	the  maximum  possible
	      address of the data segment.

       4      (Implemented  but	 no  symbolic  constant provided.)  Return the
	      maximum number of files that the calling process can open.

RETURN VALUE
       On success, ulimit() returns a nonnegative  value.   On	error,	-1  is
       returned, and errno is set appropriately.

ERRORS
