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
pthread_attr_getstack(3), is always a pointer to the
lowest address in the allocated stack area (and the
