posix_spawnattr_getstackmax()

Get the maximum stack size attribute from a spawn attributes object

Synopsis:

#include <spawn.h>

int posix_spawnattr_getstackmax(
       const posix_spawnattr_t *_Restrict attrp,
       uint32_t *_Restrict size_p);

Arguments:

attrp: A pointer to the spawn attributes object that you want to query.
size_p: A pointer to a location where the routine can store the current maximum stack size.

Library:

libc

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

Description:

The posix_spawnattr_getstackmax() function retrieves the maximum stack size attribute from the given spawn attributes object. 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(). The default is no maximum.

To set the value of this attribute, call posix_spawnattr_setstackmax().

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