Function avr_libc::setjmp

pub unsafe extern "C" fn setjmp(__jmpb: *mut _jmp_buf) -> i16

\ingroup setjmp \brief Save stack context for non-local goto.

\code #include <setjmp.h>\endcode

setjmp() saves the stack context/environment in \e __jmpb for later use by longjmp(). The stack context will be invalidated if the function which called setjmp() returns.

\param __jmpb Variable of type \c jmp_buf which holds the stack information such that the environment can be restored.

\returns setjmp() returns 0 if returning directly, and non-zero when returning from longjmp() using the saved context.
