Compile SD_API_SUCCESS function with error.

Hi all,

I use SD_API_SUCCESS in my function like this :
"
SD_API_STATUS My_function (para,.....)
{
SD_API_STATUS RequestStatus;
......
......
if (!SD_API_SUCCESS(RequestStatus)){
return RequestStatus;
}
}
"
When I build my driver, system report :

error C2220: warning treated as error - no 'object' file generated
: [01:0000000036:WARNN ] d:\wince500\public\common\oak\drivers\sds\xxxx.cpp(
warning C4715: 'My_function': not all control paths return a value

I also found that if I comment the SD_API_SUCCESS function and let
My_function return RequestStatus directly, like this :
"
SD_API_STATUS My_function (para,.....)
{
SD_API_STATUS RequestStatus;
......
......
return RequestStatus;
}
"
then, it can be build successfully.

Do you know what's the matter in My_function ? Thanks for your help.

return SomeResult;
}
