Name | Description
longjmp | Header File setjmp.h Category Miscellaneous Routines Prototype void longjmp(jmp_buf jmpb, int retval); Description Performs nonlocal goto. A call to longjmp restores the task state captured by the last call to setjmp with the argument jmpb. It then returns in such a way that setjmp appears to have returned with the value retval. A Win32 task state includes: Register variables EBX, EDI, ESI Stack pointer (ESP) Frame pointer (EBP) No segment registers are saved Flags are not saved A task state is complete enough that setjmp and longjmp can be used to implement co-routines. setjmp must be called before longjmp.

setjmp | Header File setjmp.h Category Miscellaneous Routines Prototype int setjmp(jmp_buf jmpb); Description Sets up for nonlocal goto. setjmp captures the complete task state in jmpb and returns 0. A later call to longjmp with jmpb restores the captured task state and returns in such a way that setjmp appears to have returned with the value val. Under Win32, a task state includes: No segment registers are saved Register variables EBX, EDI, ESI Stack pointer (ESP) Frame pointer (EBP) Flags are not saved A task state is complete enough that setjmp can be used to implement co-routines. setjmp must be called before... more
