Macro Definition Documentation

◆ PASTE

#define PASTE (   a,
 
)    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.

)    a ## b
