This enumeration identifies the calling convention used by a method described in the METHODDATAstructure.

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 CALLCONVenumeration.

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.
