I don't think you need to do fancy #ifdef's:
static s32 return_eio_32(void) { return -EIO; } static s64 return_eio_64(void) { return -EIO; } extern void return_eio_unknown(void); /* Doesn't exist */ #define return_eio(type) ((sizeof(type) == 4) \ ? ((void *) return_eio_32) \ : ((sizeof(type) == 8) \ ? ((void *) return_eio_64) \ : ((void *) return_eio_unknown)))
