pthread_attr_getstackaddr, pthread_attr_setstackaddrthread attribute operations

#include <pthread.h>

int
pthread_attr_getstackaddr(const pthread_attr_t *restrict attr, void **restrict stackaddr);

int
pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);

Thread attributes are used to specify parameters to (). One attribute object can be used in multiple calls to pthread_create(), with or without modifications between calls.

The functions () and () respectively, set and get the address at which the stack of the newly created thread should be located. The stackaddr attribute is set within the attr argument, which can subsequently be used as an argument to pthread_create().

If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. pthread_attr_getstackaddr() returns the stackaddr attribute value in stackaddr if successful.

pthread_attr_setstackaddr() will fail if:

[]
Invalid value for attr.

pthread_attr_getstackaddr() will fail if:

[]
Invalid value for attr.
