pthread_attr_setstackaddr Subroutine

Purpose

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

Library

Threads Library (libpthreads.a)

Syntax

#include <pthread.h>

int pthread_attr_setstackaddr (attr, stackaddr)

pthread_attr_t *attr;

void *stackaddr;

Description

The pthread_attr_setstackaddr subroutine sets the value of the stackaddr
attribute of the thread attributes object attr. This attribute specifies the
stack address of a 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 Specifies the stack address to set. It is a void pointer.

Return Values

Upon successful completion, 0 is returned. Otherwise, an error code is returned.

Error Codes

The pthread_attr_setstackaddr subroutine is unsuccessful if the following is
true:

EINVAL The attr parameter is not valid.

ENOSYS The stack address POSIX option is not implemented.

Implementation Specifics

This subroutine is part of the Base Operating System (BOS) Runtime.
