This enumeration identifies the calling convention used by a method described in the METHODDATA structure.
Syntax
typedef enum tagCALLCONV {
CC_CDECL = 1,
CC_MSCPASCAL = 2,
CC_PASCAL = CC_MSCPASCAL,
CC_MACPASCAL = 3,
CC_STDCALL = 4,
CC_RESERVED = 5,
CC_SYSCALL = 6,
CC_MPWCDECL = 7,
CC_MPWPASCAL = 8,
CC_MAX = 9
} CALLCONV;
Elements
- CC_CDECL
Indicates that the Cdecl calling convention is used for a method.
- CC_MSCPASCAL
Indicates that the Mscpascal calling convention is used for a method.
- CC_PASCAL
Indicates that the Pascal calling convention is used for a method.
- CC_MACPASCAL
Indicates that the Macpascal calling convention is used for a method.
- CC_STDCALL
Indicates that the Stdcall calling convention is used for a method.
- CC_RESERVED
Reserved for future use.
- CC_SYSCALL
Indicates that the Syscall calling convention is used for a method.
- CC_MPWCDECL
Indicates that the Mpwcdecl calling convention is used for a method.
- CC_MPWPASCAL
Indicates that the Mpwpascal calling convention is used for a method.
- CC_MAX
Indicates the end of the CALLCONV enumeration.
Remarks
On 16-bit Windows systems, functions implemented with the CC_CDECL calling convention cannot have a return type of float or double. This includes functions that retrieve a DATE type, which is a floating-point type.
