The environment of a call to setjmp consists ofinformation sufficient for a call to the longjmp function to return execution to thecorrect block and invocation of that block, were it called recursively. It does not includethe state of the floating-point status flags, of open files, or of any other component ofthe machine.jmp_buf conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).See also longjmp (page 277), setjmp (page 277)276 Chapter 28 Standard C Library Reference
