ULIMIT(3) Linux Programmer's Manual ULIMIT(3)
ulimit - get and set user limits
long ulimit(int cmd, long newlimit);
Warning: This routine is obsolete.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.
Return the limit on the size of a file, in units of 512 bytes.
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.
On success, ulimit() returns a nonnegative value. On error, -1 is returned, and errno is set appropriately.
EPERM A unprivileged process tried to increase a limit.
SVr4, POSIX.1-2001. POSIX.1-2008 marks ulimit() as obsolete.
bash(1), getrlimit(2), setrlimit(2), sysconf(3)
