ulimit
ULIMIT(3) Linux Programmer's Manual ULIMIT(3)
NAME
ulimit - get and set user limits
SYNOPSIS
#include <ulimit.h>
long ulimit(int cmd, long newlimit);
DESCRIPTION
Warning: This routine is obsolete. 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 calling 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 unprivileged process tried to increase a limit.
CONFORMING TO
SVr4, POSIX.1-2001. POSIX.1-2008 marks ulimit() as obsolete.
SEE ALSO
