I'm calling several function defined in task.c from mains.c but compiler produce a warning for 3 function the following warning

..\MAINS.C(476): warning C206: 'Page_Down_MarkTask_IR': missing function-prototype
..\MAINS.C(486): warning C206: 'Volume_Up_MarkTask_IR': missing function-prototype
..\MAINS.C(497): warning C206: 'Volume_Down_MarkTask_IR': missing function-prototype

but I also use Menu_Marktask_IR() in mains.c function which declared in task.h for this function no warning and for 3 functions above compiler produce warning.

Somebody have an idea

    It's not about double underscored "files" but rather about double-underscored macro names. The fact that you didn't run into problem with these only means that you've been lucky so far (or that you failed to notice the breakage).

    It doesn't matter whether they're your "personal" header files or some other programmer's: if they're not written by your compiler vendor, they may not use this kind of name, because these names are reserved to the implementor. For the sake of this forum, the implementor is neither your, nor that other person whose code you're using, but only Keil GmbH.

    The Compiler offers a Preprint directive where a listing with the extension *.I is generated. This listing shows the code after the Preprocessor and should contains the function prototypes. It allows you to verify the header files that are included.

    If the function prototypes are not in this listing you have perhaps some #defines or other conditional preprocessor statements that make them invisible.
