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.
