Combining the value of GetLastError and a custom error message
- by Jessica
I have a function that returns a different DWORD value for each case there is an error. So I have the following defines:
#define ERR_NO_DB_CONNECTION 0x90000
#define ERR_DB_NOT_OPEN 0x90001
#define ERR_DB_LOCKED 0x90002
#define ERR_DB_CONN_LOST 0x90003
Now, I return those values when an error occurs.
I need to also return the value of GetLastError in the same return.
No, I can't read it later.
I tried combining it different ways, eg:
return ERR_DB_NOT_OPEN + GetLastError();
and then extract the error by subtracting the value of ERR_DB_NOT_OPEN but since I need to use this in functions where there can be several return values it can get quite complex to do that.
Is there any way to achieve this? I mean, combine the value + GetLastError and extract them later?
Code is appreciated.
Thanks
Jess.
