Sets the value of the macro_name macro to the value on the top of the stack for this macro.
#pragma pop_macro("
macro_name
")
Remarks
You must first issue a push_macro for macro_name before you can do a pop_macro.
// pragma_directives_pop_macro.cpp
// compile with: /W1
#include <stdio.h>
#define X 1
#define Y 2
int main() {
printf("%d",X);
printf("\n%d",Y);
#define Y 3 // C4005
#pragma push_macro("Y")
#pragma push_macro("X")
printf("\n%d",X);
#define X 2 // C4005
printf("\n%d",X);
#pragma pop_macro("X")
printf("\n%d",X);
#pragma pop_macro("Y")
printf("\n%d",Y);
