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Warning: This routine is obsolete.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 provided 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.

CONFORMING TO

SVr4, POSIX.1-2001.
