Should, for example, you have a compiler which has someone's "improved" version of ctype.h that didn't have the macro, the function would still exist at runtime for use.ĭeclared in a header may be additionally implemented as a function-like macro defined in the header, so if a library function is declared explicitly when its header is included, one This is the first comprehensive treatment of ANSI and ISO standards for the C Library. Prentice Halls most important C programming title in years. The function call allows linking against the same library even if the program was compiled without the macro definition - if it was compiled with a different header, or just with a rogue declaration inside the source file. It can be optimised more easily, as it just involves a pointer offset lookup. The macro is (putatively) more efficient, as it doesn't involve a function call.
