NAME        top

       PR_SET_MM_ARG_START, PR_SET_MM_ARG_END, PR_SET_MM_ENV_START,       PR_SET_MM_ENV_END - modify kernel memory map descriptor fields

LIBRARY        top

       Standard C library (libc,-lc)

SYNOPSIS        top

#include <linux/prctl.h>/* Definition ofPR_*constants */#include <sys/prctl.h>int prctl(PR_SET_MM, PR_SET_MM_ARG_START, unsigned longaddr, 0L, 0L);int prctl(PR_SET_MM, PR_SET_MM_ARG_END, unsigned longaddr, 0L, 0L);int prctl(PR_SET_MM, PR_SET_MM_ENV_START, unsigned longaddr, 0L, 0L);int prctl(PR_SET_MM, PR_SET_MM_ENV_END, unsigned longaddr, 0L, 0L);

DESCRIPTION        top

PR_SET_MM_ARG_START              Set the address above which the program command line is              placed.PR_SET_MM_ARG_END              Set the address below which the program command line is              placed.PR_SET_MM_ENV_START              Set the address above which the program environment is              placed.PR_SET_MM_ENV_END              Set the address below which the program environment is              placed.       The address passed with these calls should belong to a process       stack area.  Thus, the corresponding memory area must be readable,       writable, and (depending on the kernel configuration) have theMAP_GROWSDOWNattribute set (seemmap(2)).

RETURN VALUE        top

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

ERRORS        top

EINVALaddr is greater thanTASK_SIZE(the limit on the size of              the user address space for this architecture).

STANDARDS        top

       Linux.

HISTORY        top

       Linux 3.5.
