C# in a Nutshell, Second Edition

Name

CallingConvention

Synopsis

This enumeration specifies the calling convention to use when you invoke a function. DllImportAttribute uses this in its CallingConvention parameter.

Cdecl specifies the standard calling convention used by C++ and C programs. This is required for functions that take a variable number of arguments, such as printf( ). FastCall attempts to put function arguments into registers. StdCall is the convention used for calling Win32 API functions. ThisCall is the calling convention used by C++ member functions taking fixed arguments. Use the Winapi calling convention for function calls that use PASCAL or _ _far _ _pascal.

public enum CallingConvention {
   Winapi = 1,
   Cdecl = 2,
   StdCall = 3,
   ThisCall = 4,
   FastCall = 5
}
