The size of the +storage shall be at least {PTHREAD_STACK_MIN}. +.SH RETURN VALUE +.LP +Upon successful completion, \fIpthread_attr_getstackaddr\fP() and +\fIpthread_attr_setstackaddr\fP() shall return a value of 0; +otherwise, an error number shall be returned to indicate the error. +.LP +The \fIpthread_attr_getstackaddr\fP() function stores the \fIstackaddr\fP +attribute value in \fIstackaddr\fP if +successful. +.SH ERRORS +.LP +No errors are defined. +.LP +These functions shall not return an error code of [EINTR]. +.LP +\fIThe following sections are informative.\fP +.SH EXAMPLES +.LP +None. +.SH APPLICATION USAGE +.LP +The specification of the \fIstackaddr\fP attribute presents several +ambiguities that make portable use of these interfaces +impossible. 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 \fIpthread_attr_setstack\fP() and \fIpthread_attr_getstack\fP() +to resolve these ambiguities. +.SH RATIONALE +.LP +None. +.SH FUTURE DIRECTIONS +.LP +None. +.SH SEE ALSO +.LP +\fIpthread_attr_destroy\fP(), \fIpthread_attr_getdetachstate\fP(), +\fIpthread_attr_getstack\fP(), \fIpthread_attr_getstacksize\fP(), +\fIpthread_attr_setstack\fP(), \fIpthread_create\fP(), the +Base Definitions volume of IEEE\ Std\ 1003.1-2001, \fI<limits.h>\fP, +\fI<pthread.h>\fP +.SH COPYRIGHT +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.
