NAME
       stack_getbounds - retrieve stack boundaries

SYNOPSIS
       #include <ucontext.h>

       int stack_getbounds(stack_t *sp);

DESCRIPTION
       The stack_getbounds() function retrieves the stack boundaries that the calling thread is currently operating on. If the thread is currently
       operating on the alternate signal stack, this function will retrieve the bounds of that stack.

       If successful, stack_getbounds() sets the ss_sp member of the stack_t structure pointed to by sp to the base of the stack  region  and  the
       ss_size	member	to  its size (maximum extent) in bytes. The ss_flags member is set to SS_ONSTACK if the calling thread is executing on its
       alternate signal stack, and zero otherwise.

RETURN VALUES
       Upon successful completion, stack_getbounds() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS
       The stack_getbounds() function will fail if:

       EFAULT	 The sp argument does not refer to a valid address.
