ULIMIT (3)

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Warning: This routine is obsolete.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
