<LI>setjmp.h - contains defintion for ANSI setjmp &amp; longjmp routines.
Note in this case setjmp &amp; longjmp can be used between functions
executing within the same register bank, if long jmp is executed from
a function that is using a different register bank from the function
issuing the setjmp function, the results may be unpredictable. The
jump buffer requires 3 bytes of data (the stack pointer &amp; a 16 byte
return address), and can be placed in any address space.</LI>
