Get Error Contents

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

Programming Example in C

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

Ret = AioInit( "AIO000" , &Id );
ErrorRet = AioGetErrorString( Ret , ErrorString );
printf("AioInit : %s", ErrorString );

Ret = AioExit( Id );
ErrorRet = AioGetErrorString( Ret , ErrorString );
printf("AioExit : %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 = caio.AioInit ( b"AIO000" , ctypes.byref(Id) )

ErrorRet.value = caio.AioGetErrorString( Ret, ErrorString )

print( f"AioInit : {ErrorString.value.decode('sjis')}" )

Ret.value = caio.AioExit ( Id )

ErrorRet.value = caio.AioGetErrorString( Ret, ErrorString )

print( f"AioExit : {ErrorString.value.decode('sjis')}" )
