posix_spawnattr_setstackmax()

Set the maximum stack size attribute in a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_setstackmax(
       posix_spawnattr_t *attrp,
       uint32_t size );

Arguments:

attrp
A pointer to the spawn attributes object that you want to modify.
size
The maximum stack size that you want to use for the spawned processes

Library:

libc

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

Description:

The posix_spawnattr_setstackmax() function sets the maximum stack size attribute in the given spawn attributes object. The default is no maximum. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().

This setting takes effect only if the POSIX_SPAWN_SETSTACKMAX flag is set in the spawn attributes; to set this flag, call posix_spawnattr_setxflags().

To retrieve the value of this attribute, call posix_spawnattr_getstackmax().

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


Note: This function is a QNX Neutrino extension.

Returns:

EOK

EINVAL
An argument was invalid.

Classification:

QNX Neutrino
