Override windows function in mixed c and c++ program
Posted on 2008-10-13
I have an application that has both c and c++ files. I have written some functions that I want to over ride some windows functions, namely Registry calls. For example i have a function called my_RegCreateEx and what I want is that when my code calls RegCreateEx I want the call to go to my_RegCreateEx and not the windows default RegCreateEx found in winreg.h.
I have created my_RegCreateEx() function call in a cpp file and used the extern "c" in the my header file, call it my_reg.h. Also in another header file, call it my_functions.h I have a defined as follows:
#define my_RegCreateEx RegCreateEx. Now in any cpp file that I have:
where I have a call to RegCreateEx() the code will go to my function my_RegCreateEx() as expected but in any C files where I have a RegCreateEx() call it goes to the windows function, which I do not want.
I need help where no matter what type of file, C or C++, the RegCreateEx call will always go to my_RegCreateEx call.
Thanks for you help
