This header was originally in the C standard library as <setjmp.h>.

This header is part of the program support library.

Types
jmp_buf	execution context type (typedef)
Macros
setjmp	saves the context (function macro)
Functions
longjmp	jumps to specified location (function)

Synopsis

namespace std {
  using jmp_buf = /* see description */ ;
  [[noreturn]] void longjmp(jmp_buf env, int val);
}
#define setjmp(env) /* see description */
