PTHREAD_ATTR_GETSTACKADDR(3C) Standard C Library Functions

NAME


pthread_attr_getstackaddr, pthread_attr_setstackaddr - get or set
stackaddr attribute

SYNOPSIS


cc -mt [ flag... ] file... -lpthread [ library... ]
#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);


DESCRIPTION


The functions pthread_attr_setstackaddr() and
pthread_attr_getstackaddr(), respectively, set and get the thread
creation stackaddr attribute in the attr object. The stackaddr default is
NULL. See pthread_create(3C).


The stackaddr attribute specifies the location of storage to be used for
the created thread's stack. The size of the storage is at least
PTHREAD_STACK_MIN.

RETURN VALUES


Upon successful completion, pthread_attr_setstackaddr() and
pthread_attr_getstackaddr() return a value of 0. Otherwise, an error
number is returned to indicate the error.


If successful, the pthread_attr_getstackaddr() function stores the
stackaddr attribute value in stackaddr.

ERRORS


The pthread_attr_setstackaddr() function may fail if:

EINVAL
attr is invalid.


The pthread_attr_getstackaddr() function may fail if:

EINVAL
attr or stackaddr is invalid.
