/*
* ------------------------------------------------------
* DOCPUBLIC
* Threads created with 'attr' will run on the stack
* starting at 'stackaddr'.
* Stack must be at least PTHREAD_STACK_MIN bytes.
*
* PARAMETERS
* attr
* pointer to an instance of pthread_attr_t
*
* stackaddr
* the address of the stack to use
*
*
* DESCRIPTION
* Threads created with 'attr' will run on the stack
* starting at 'stackaddr'.
* Stack must be at least PTHREAD_STACK_MIN bytes.
*
* NOTES:
* 1) Function supported only if this macro is
* defined:
*
* _POSIX_THREAD_ATTR_STACKADDR
*
* 2) Create only one thread for each stack
* address..
*
* 3) Ensure that stackaddr is aligned.
*
* RESULTS
* 0 successfully set stack address,
* EINVAL 'attr' is invalid
* ENOSYS function not supported
*
