Does anyone have longjmp/setjmp written for microsoft lattice C?
I'd sure appreciate geting a version - there doesn't appear to
be one provided with the package.

Then a later call to longjmp will return to the next statement after the original setjmp call with value as the return code. If value is 0, it is forced to 1 by longjmp. The jmp_buf descriptor is defined in the header file called setjmp.h. This mechanism is useful for quickly popping back up through multiple layers of function calls under exceptional circumstances. (All text taken from page 33 of Lattice's supplement for version 2.10) I'd recommend you pick up the latest release (2.14) so you can take advantage of their new features. David P.
