NAME

     stack_inbounds - determine if address is within stack  boun-
     daries

SYNOPSIS

     #include <ucontext.h>

     int stack_inbounds(void *addr);

DESCRIPTION

     The stack_inbounds() function returns a boolean value  indi-
     cating  whether  the address specified by addr is within the
     boundaries of the stack of the calling thread.  The  address
     is  compared to the stack boundary information returned by a
     call to stack_getbounds(3C).

RETURN VALUES

     The stack_inbounds() function returns  0  to  indicate  that
     addr  is  not within the current stack bounds, or a non-zero
     value to indicate that addr is within the stack bounds.

ERRORS

     No errors are defined.
