Standard C library (libc, -lc)
#include <linux/prctl.h> /* Definition of PR_* constants */
#include <sys/prctl.h>
int prctl(PR_SET_MM, PR_SET_MM_START_CODE, unsigned long addr, 0L, 0L);
int prctl(PR_SET_MM, PR_SET_MM_END_CODE, unsigned long addr, 0L, 0L);
PR_SET_MM_START_CODE
Set the address above which the program text can run. The
corresponding memory area must be readable and executable,
but not writable or shareable (see mprotect(2) and mmap(2)
for more information).
PR_SET_MM_END_CODE
Set the address below which the program text can run. The
corresponding memory area must be readable and executable,
but not writable or shareable.
On success, 0 is returned. On error, -1 is returned, and errno
is set to indicate the error.
EINVAL addr is greater than TASK_SIZE (the limit on the size of
the user address space for this architecture).
EINVAL The permissions of the corresponding memory area are not
as required.
