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       Warning:	 This routine is obsolete.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
	      Return the limit on the size of a file, in units of 512  bytes.

       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
       EPERM  A non-root process tried to increase a limit.
