You really are checking whether sigsetjmp is declared and you can compile with it, not whether it is a function and you can link with it.But supposing that I wanted to pass around a pointer to it, that wouldn't help much.How do you pass around a pointer to an entity which is implemented as a preprocessor macro?
My comment was in the context of a check for stat(). If you read my earlier comment, you should have guessed that I'd read the comments on the opengroup webpage regarding setjmp(). -- Thomas E. Dickey http://invisible-island.net ftp://invisible-island.net
