A new implementation of the setjmp function.
int _setjmp3( OUT jmp_buf env, int count, (optional parameters) );
Address of the buffer for storing state information.
The number of additional DWORDs of information that are stored in the optional parameters.
Additional data pushed down by the setjmp intrinsic. The first DWORD is a function pointer that is used to unwind extra data and return to a nonvolatile register state. The second DWORD is the try level to be restored. Any further data is saved in the generic data array in the jmp_buf.
Do not use this function in a C++ program. It is an intrinsic function that does not support C++. For more information about how to use setjmp, see Using setjmp/longjmp.
