Get Error Contents

By using function DioGetErrorString, it is possible to convert error code to a character string for all functions.
The character string used by function DioGetErrorString is 256 bytes at most.

Programming Example in C

long Ret;
long ErrorRet;
short Id;
char ErrorString[256];

Ret = DioInit( "DIO000" , &Id );
ErrorRet = DioGetErrorString( Ret , ErrorString );
printf("DioInit ：%s", ErrorString );

Ret = DioExit( Id );
ErrorRet = DioGetErrorString( Ret , ErrorString );
printf("DioExit ：%s", ErrorString );

Programming Example in Python

Ret = ctypes.c_long()
ErrorRet = ctypes.c_long()
Id = ctypes.c_short()
ErrorString = ctypes.create_string_buffer(256)

Ret.value = cdio.DioInit ( b"DIO000" , ctypes.byref(Id) )
ErrorRet.value = cdio.DioGetErrorString( Ret, ErrorString )
print( f"DioInit : {ErrorString.value.decode('sjis')}" )

Ret.value = cdio.DioExit ( Id )
ErrorRet.value = cdio.DioGetErrorString( Ret, ErrorString )
print( f"DioExit : {ErrorString.value.decode('sjis')}" )
