3.94 longjmp

Function

Non local goto.

Header

setjmp.h

Declaration

void __fastcall__ longjmp (jmp_buf buf, int retval);

Description

The longjmp function restores a program context from the data in buf, which must have been set by a preceeding call to setjmp. Program execution continues as if the call to setjmp has just returned the value retval.

Limits

• If the parameter retval is zero, the function will behave as if it was called with a value of one.
• The function is only available as fastcall function, so it may only be used in presence of a prototype.

Availability

ISO 9899
