Windows API Return Code Values

Question

I am developping a small program based on the .Net framework 4 and by using the C# language.
I am using a .Net library which itself uses functions from the AVIFile Windows API.

I have got an error when using the AVIStreamRead function.
Here is the MSDN documentation for the AVIStreamRead function :
http://msdn.microsoft.com/en-us/library/windows/desktop/dd756849(v=vs.85).aspx

I want to get more information about my error from the result integer value.
The documentation page lists the three following return codes :

• AVIERR_BUFFERTOOSMALL
• AVIERR_MEMORY
• AVIERR_FILEREAD

But where do I get the corresponding integer values ?

Answer 1

Yo can get them from Vfw.h.

#define AVIERR_UNSUPPORTED      MAKE_AVIERR(101)
#define AVIERR_BADFORMAT        MAKE_AVIERR(102)
#define AVIERR_MEMORY           MAKE_AVIERR(103)
#define AVIERR_INTERNAL         MAKE_AVIERR(104)
...

To convert SCODE to error code you can use

WORD SCODE_CODE(SCODE sc);
