    I have a macro that looks like:

    #define STUB_OS_API_CALLS

    #ifndef
    STUB_OS_API_CALLS
    #define OSAPICALL(osapifunc) (osapifunc)
    #else
    #include "..\os\vcsupport\include\vcintegrityosstubs.h"
    #define OSAPICALL(osapifunc) (stub_##osapifunc)
    #endif

    when I use the macro as follows:
    eErr = OSAPICALL( Function1(a, b, &c) );

    It has no problem on expanding, however when I try to use the macro inside the first macro as follows:

    eErr = OSAPICALL( Function2(
    OSAPICALL( Function3() ),
    a,
    false,
    b,
    &c) );


    I get a compilation error, saying that OSAPICALL is not defined

    If I dont define STUB_OS_API_CALLS the Macro works just fine using the two statements shown above.

    Can anybody please help me discovering why I can't do this macro when defining STUB_OS_API_CALLS?
