Standard C Library Functions                  stack_setbounds(3C)



NAME
     stack_setbounds - update stack boundaries

SYNOPSIS
     #include 

     int stack_setbounds(const stack_t *sp);


DESCRIPTION
     The stack_setbounds() function updates the current base  and
     bounds  of  the  stack  for the current thread to the bounds
     specified by the stack_t structure pointed  to  by  sp.  The
     ss_sp  member  refers  to the virtual address of the base of
     the stack memory. The ss_size member refers to the  size  of
     the stack in bytes. The ss_flags member must be set to 0.

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

ERRORS
     The stack_setbounds() function will fail if:

     EFAULT    The sp argument does not refer to a valid  address
               or  the  ss_sp  member  of  the  stack_t structure
               pointed to by sp points to an illegal address.


     EINVAL    The ss_sp member of the stack_t structure  pointed
               to  by  sp  is  not  properly aligned, the ss_size
               member is too small or is not properly aligned, or
               the ss_flags member is non-zero.


USAGE
     The stack_setbounds() function is intended for use by appli-
     cations that are managing their own alternate stacks.
