PTHREAD_ATTR_SETSTACKADDRSection: Linux Programmer's Manual (3)
NAMEpthread_attr_setstackaddr, pthread_attr_getstackaddr - set/get stack address attribute in thread attributes object
#include <pthread.h>int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);int pthread_attr_getstackaddr(const pthread_attr_t *attr, void **stackaddr);Compile and link with -pthread.
DESCRIPTIONThese functions are obsolete: do not use them.Use pthread_attr_setstack(3) and pthread_attr_getstack(3) instead.
The pthread_attr_setstackaddr() function sets the stack address attribute of the thread attributes object referred to by attrto the value specified in stackaddr. This attribute specifies the location of the stack that should be used by a thread that is created using the thread attributes object attr.
stackaddrshould point to a buffer of at least PTHREAD_STACK_MINbytes that was allocated by the caller. The pages of the allocated buffer should be both readable and writable.
RETURN VALUEOn success, these functions return 0; on error, they return a nonzero error number.
ERRORSNo errors are defined (but applications should nevertheless handle a possible error return).
VERSIONSThese functions are provided by glibc since version 2.1.
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).

CONFORMING TOPOSIX.1-2001 specifies these functions but marks them as obsolete. POSIX.1-2008 removes the specification of these functions.
NOTESDo not use these functions!They cannot be portably used, since they provide no way of specifying the direction of growth or the range of the stack. For example, on architectures with a stack that grows downward, stackaddrspecifies the address past the highestaddress of the allocated stack area. However, on architectures with a stack that grows upward, stackaddrspecifies the lowestaddress in the allocated stack area. By contrast, the stackaddrused by pthread_attr_setstack(3) and pthread_attr_getstack(3), is always a pointer to the lowest address in the allocated stack area (and the stacksizeargument specifies the range of the stack).
