If it's a procedure, you need to tell the compiler to not name mangle
it... wrap the prototype with:
#ifdef __cplusplus
extern "C" {
#endif
(void) myFunction(void);
#ifdef __cplusplus
}
#endif

Firstly, many thanks to everybody for helping.
So here is a new problem.
I have a ".c++" file with a procedure called from a ".m" file
(Cocoa). But XCode tells me "undefined symbol" when linking (I
turned off ZeroLink).
Let's say I have
theCFile.h declaring theCProcedure,
theCFile.c++ containing theCProcedure
and theCocoaFile.m calling theCProcedure.
All files are in the same project; when building everything seems
ok; I set "#include "theCFile.h"" in theCocoaFile.m; the target of
theCFile.c++ is the target application...
I shouldn't be surprised if it couldn't link with some libraries
called from theCFile.c++, but linking with theCFile.o?
Can you help some way?
Many thanks again,
regards, livio.
