ULIMIT(3C)              COMMAND REFERENCE              ULIMIT(3C)



NAME
     ulimit - get and set user limits

SYNOPSIS
     long ulimit (cmd, newlimit)
     int cmd;
     long newlimit;

DESCRIPTION
     This function provides for control over process limits.  The
     cmd values available are:

          1  Get the process's file size limit.  The limit is in
             units of 512-byte blocks and is inherited by child
             processes.  Files of any size can be read.

          2  Set the process's file size limit to the value of
             newlimit.  Any process may decrease this limit, but
             only a process with an effective user ID of
             superuser may increase the limit.  Ulimit will fail
             and the limit will be unchanged if a process with an
             effective user ID other than superuser attempts to
             increase its file size limit.  [EPERM]

          3  Get the maximum possible break value (in bytes).
             See brk(2).

RETURN VALUE
     Upon successful completion, a nonnegative value is returned.
     Otherwise, a value of -1 is returned and errno is set to
     indicate the error.
