我想做一个包含#pragma
指令的#define
,但我得到了以下错误。知道吗?
#define FunctionPar_Begin typedef struct fpar { #pragma pack(4)
error C2121: '#': invalid character: possibly the result of a macro expansion
您可能想要的:
#define FunctionPar_Begin typedef struct fpar { _Pragma("pack(4)")
MSVC还允许:
#define FunctionPar_Begin typedef struct fpar { __pragma(pack(4))
Clang/gcc还允许:
#define FunctionPar_Begin typedef struct fpar { __attribute__((packed, aligned(4)))
