pthread_attr_getstackaddr Subroutine

Purpose

Returns the value of the stackaddr attribute of a thread attributes object.

Library

Threads Library (libpthreads.a)

Syntax

#include <pthread.h>

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

Description

The pthread_attr_getstackaddr subroutine returns the value of the stackaddr attribute of the thread attributes object attr. This attribute specifies the stack address of the thread created with this attributes object.

Note

The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.

Parameters

attr	Specifies the thread attributes object.
stackaddr	Points to where the stackaddr attribute value will be stored.

Return Values

Upon successful completion, the value of the stackaddr attribute is returned via the stackaddr parameter, and 0 is returned. Otherwise, an error code is returned.

Error Codes

The pthread_attr_getstackaddr subroutine is unsuccessful if the following is true:

EINVAL

The attr parameter is not valid.

This function will not return EINTR.
