getustack(2)                     System Calls                     getustack(2)



NAME
       getustack,  setustack - retrieve or change the address of per-LWP stack
       boundary information

SYNOPSIS
       #include <ucontext.h>

       int getustack(stack_t **spp);


       int setustack(stack_t *sp);

DESCRIPTION
       The getustack() function retrieves the address of per-LWP stack  bound‐
       ary  information.  The  address is stored at the location pointed to by
       spp. If this address has not been defined  using  a  previous  call  to
       setustack(), NULL is stored at the location pointed to by spp.


       The  setustack()  function  changes the address of the current thread's
       stack boundary information to the value of sp.

RETURN VALUES
       Upon successful completion, these functions return 0. Otherwise, −1  is
       returned and errno is set to indicate the error.

ERRORS
       These functions will fail if:

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


USAGE
       Only  implementors of custom threading libraries should use these func‐
       tions to get and set the address of the stack bound to an internal per-
       thread  data  structure. Other users should use stack_getbounds(3C) and
       stack_setbounds(3C).
