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.

Implementation Specifics

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