Token-pasting macros.
Definition in file tokpaste.h.
#define PASTE | ( | a, | |
b | |||
) | PASTE__(a,b) |
Concatenate a
and b
in a way that allows their result itself to be expanded by the preprocessor.
Ordinarily you could just say a ## b
in a macro definition. But doing so results in a symbol which the preprocessor will not then expand. If you wanted to use a ## b
to create the name of a macro and have the preprocessor expand that macro, you need to have another level of indirection, as this macro provides.
