posix_spawnattr

Control how the Address Space Layout Randomization (ASLR) setting of a child is determined

Synopsis:

#include <spawn.h>

int posix_spawnattr_setaslr(
       posix_spawnattr_t * attrp,
       posix_spawnattr_aslr_t aslr);

Arguments:

attrp

A pointer to the opaque spawn attributes object.

aslr

The ASLR setting; one of:

POSIX_SPAWN_ASLR_DEFAULT: The process inherits its parent's settings (equivalent to not setting the attribute).
POSIX_SPAWN_ASLR_ENABLE: Enable ASLR.
POSIX_SPAWN_ASLR_DISABLE: Disable ASLR.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The posix_spawnattr_setaslr() function sets the value of the Address Space Layout Randomization (ASLR) setting in the spawn attributes object that attrp points to. You must have already initialized this object by calling posix_spawnattr_init().

For more information about spawn attributes, see the entry for posix_spawn().

Returns:

EOK: Success.
EINVAL: The handle is not a valid attributes object or aslr is invalid.
