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

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.
