NAME

pthread_attr_getstackaddr, pthread_attr_setstackaddr– get or set stackaddr attribute

SYNOPSIS

cc –mt [ flag... ] file... –lpthread [ -lrt library... ]
#include <pthread.h>

int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
int pthread_attr_getstackaddr(const 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(3THR).

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.
