Typechecking macro arguments in C
- by Rocketmagnet
Hi all,
Is is possible to typecheck arguments to a #define macro? For example:
typedef enum
{
REG16_A,
REG16_B,
REG16_C
}REG16;
#define read_16(reg16) read_register_16u(reg16); \
assert(typeof(reg16)==typeof(REG16));
The above code doesn't seem to work. What am I doing wrong?
BTW, I am using gcc, and I can guarantee that I will always be using gcc in this project. The code does not need to be portable.
