NAME

       PR_SET_MM_BRK - modify kernel memory map descriptor fields

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <linux/prctl.h>  /* Definition of PR_* constants */
       #include <sys/prctl.h>

       int prctl(PR_SET_MM, PR_SET_MM_BRK, unsigned long addr, 0L, 0L);

DESCRIPTION

       Set the current brk(2) value.

       The requirements for the address are the same as for the PR_SET_MM_START_BRK option.

RETURN VALUE

       On success, 0 is returned.  On error, -1 is returned, and errno is set to indicate the error.

ERRORS

       EINVAL addr  is  greater  than  TASK_SIZE  (the  limit  on  the  size  of the user address space for this
              architecture).

       EINVAL addr is less than or equal to the end of the data segment or specifies a value  that  would  cause
              the RLIMIT_DATA resource limit to be exceeded.

STANDARDS

       Linux.

HISTORY

       Linux 3.3.
