     The function sets the stack address attribute of the
thread attributes object referred to by attr to the value
specified in This attribute specifies the location of the
stack that should be used by a thread that is created using
the thread attributes object

     stackaddr should point to a buffer of at least
PTHREAD_STACK_MIN bytes that was allocated by the caller.
The pages of the allocated buffer should be both readable
and writable.

     The function returns the stack address attribute of the
thread attributes object referred to by attr in the buffer
pointed to by

On success, these functions return 0; on error, they return
a nonzero error number.

No errors are defined (but applications should nevertheless
handle a possible error return).

These functions are provided by glibc since version 2.1.

POSIX.1‐2001 specifies these functions but marks them as
obsolete.  POSIX.1‐2008 removes the specification of these
functions.

useDonot 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, stackaddr specifies the next address past
the highest address of the allocated stack area.  However,

on architectures with a stack that grows upward, stackaddr
specifies the lowest address in the allocated stack area.
By contrast, the stackaddr used by and is always a pointer
to the lowest address in the allocated stack area (and the
stacksize argument specifies the range of the stack).
