The description of the single address parameter as a +"stack" does not specify a particular relationship between +the address and the "stack" implied by that address. For +example, the address may be taken as the low memory address of a +buffer intended for use as a stack, or it may be taken as the address +to be used as the initial stack pointer register value for the new +thread. These two are not the same except for a machine on which the +stack grows "up" from low memory to high, and on which a +"push" operation first stores the value in memory and then +increments the stack pointer register. Further, on a machine where +the stack grows "down" from high memory to low, +interpretation of the address as the "low memory" address +requires a determination of the intended size of the stack. +IEEE Std 1003.1-2001 has introduced the new interfaces +<A HREF="pthread_attr_setstack.html"><B>pthread_attr_setstack</B>(3)</A> +and <A HREF="pthread_attr_getstack.html"><B>pthread_attr_getstack</B>(3)</A> +to resolve these ambiguities. +</P> +<H2><A HREF="#toc7" NAME="sect7">Rationale</A></H2> +<P>None. +</P> +<H2><A HREF="#toc8" NAME="sect8">Future Directions</A></H2> +<P>None. +</P> +<H2><A HREF="#toc9" NAME="sect9">See Also</A></H2> +<P><A HREF="pthread_attr_init.html"><B>pthread_attr_destroy</B>(3)</A> +, <A HREF="pthread_attr_init.html"><B>pthread_attr_getdetachstate</B>(3)</A> +, <A HREF="pthread_attr_getstack.html"><B>pthread_attr_getstack</B>(3)</A> +, <A HREF="pthread_attr_getstacksize.html"><B>pthread_attr_getstacksize</B>(3)</A> +, <A HREF="pthread_attr_setstack.html"><B>pthread_attr_setstack</B>(3)</A> +, <A HREF="pthread_create.html"><B>pthread_create</B>(3)</A> , the +Base Definitions volume of IEEE Std 1003.1-2001, +<I><limits.h></I>, <I><pthread.h></I> +</P> +<H2><A HREF="#toc10" NAME="sect10">Copyright</A></H2> +<P>Portions of this text are reprinted and reproduced in electronic +form from IEEE Std 1003.1, 2003 Edition, Standard for Information +Technology -- Portable Operating System Interface (POSIX), The Open +Group Base Specifications Issue 6, Copyright (C) 2001-2003 by the +Institute of Electrical and Electronics Engineers, Inc and The Open +Group.
