Retrieves the total number of PWM output channels of the device.
Ret = DioGetMaxPwmChannels ( Id , ChannelNum )
Id [ VB.NET： Short ] [ C, C++： short ] [ C#： short ] [ Python: ctypes.c_short ]
Specify the device ID retrieved from DioInit.
ChannelNum [ VB.NET： UShort ] [ C, C++： unsigned short * ] [ C#： out ushort ] [ Python: ctypes.POINTER(ctypes.c_ushort) ]
Specify the address of the variable to obtain the number of PWM output channels.
Ret [ VB.NET： Integer ] [ C, C++： long ] [ C#： int ] [ Python: ctypes.c_long ]
