6.60.12. Push/Pop Macro Pragmas
6.60.12 Push/Pop Macro Pragmas
For compatibility with Microsoft Windows compilers, GCC supports ‘#pragma push_macro("macro_name")’ and ‘#pragma pop_macro("macro_name")’.
-
#pragma push_macro(
"macro_name")
- This pragma saves the value of the macro named as macro_name to the top of the stack for this macro.
-
#pragma pop_macro(
"macro_name")
- This pragma sets the value of the macro named as macro_name to the value on top of the stack for this macro. If the stack for macro_name is empty, the value of the macro remains unchanged.
For example:
#define X 1 #pragma push_macro("X") #undef X
