Shared Functions Declaration

[ajorge]

Good Morning!

I have some code done in C. I'm building it using Visual C++, but there are some errors like:

Error 1 error C2054: expected '(' to follow 'SHARED_FUNCTION'
Error 2 error C2085: 'le16ToHost' : not in formal parameter list


The function is declared like this:

SHARED_FUNCTION WORD le16ToHost( BYTE * src );

There's any problem with the way i'm declaring de function? Shared Functions are different in Visual C++?

Best regards.

The function is declared like this:

SHARED_FUNCTION WORD le16ToHost( BYTE * src );

What is SHARED_FUNCTION? I never saw it MSDN nor somewhere else.
Where and how is it #defined?

And make sure your C file has cpp extension before building.

And make sure your C file has cpp extension before building.

although that is convention (IF the program is a C++ program [which has NOT been stated!!!!]), it is not a requirement, and I can not see how this has ANYTHING to do with the posters problem....

Hi to all! I'm sorry for the few information i've writen

The definition is:

#ifndef __COMPILER_H
#define __COMPILER_H



//-----------------------------------------------------------------------------
//
//Windows Compiler specific section: This should be extracted to the
//SMAlib system for compiler specific definitions. But first do it here....

//##### Microsoft Compiler specific #####
#if defined ( _MSC_VER ) || defined ( MSVCPP )

//to reduce some define stuff...
#define USING_MICROSOFT_COMPILER

//don't ask....
#if defined(_DLL) || defined (_WINDLL)
#define __DLL__ 1
#endif

//building an DLL? => Mark functions with "export"

#ifdef __DLL__
#define SHARED_FUNCTION __declspec(dllexport)

#endif

//disable all deprecation warnings,
#if (_MSC_VER >= 1400) // VC8+
#pragma warning(disable : 4996)

//define it for the rest....

#endif

#endif

//for precompield head with borland compilers...stop caching here...
#pragma hdrstop

#endif


//##### GNU C compiler specific Windows #####
#ifdef __GNUC__
#ifdef _WIN32

#endif

#endif



#endif /*__COMPILER_H*/


The function declaration is:

SHARED_FUNCTION WORD le16ToHost( BYTE * src );

And the function definition is:

WORD le16ToHost( BYTE * src )
{
return ((src[0] ) | (src[1]<<8 ));
}

The errors were the mentioned before in my first post.

Best Regards.

[Alin]

so how are you using le16ToHost in your code?

I'm trying to create a dll file using this function and others of the same type.

Thanks! I already detect the problem origin. It was the compiler selection routine. Wasn't working

Best regards.
