[Dev-C++] Use dll libraries with Dev-C++

[Pedro S. <ped...@gm...>]

Hi,

Sorry for the silly question, but I've not find the solution throw googling.

How can I use dll files in a Dev-C++ project. I need to use functions
declared in a dll file and I didn't found how can I do it.

Thanks in advance

Example at http://en.wikipedia.org/wiki/Dynamic_link_library:

#include <windows.h>
#include <stdio.h>

// DLL function signature
typedef double (*importFunction)(double, double);

int main(int argc, char **argv)
{
        importFunction addNumbers;
        double result;

        // Load DLL file
        HINSTANCE hinstLib = LoadLibrary("Example.dll");
        if (hinstLib == NULL) {
                printf("ERROR: unable to load DLL\n");
                return 1;
        }

        // Get function pointer
        addNumbers = (importFunction)GetProcAddress(hinstLib, "AddNumbers");
        if (addNumbers == NULL) {
                printf("ERROR: unable to find DLL function\n");
               FreeLibrary(hinstLib);
                return 1;
        }

        // Call function.
        result = addNumbers(1, 2);

        // Unload DLL file
        FreeLibrary(hinstLib);

        // Display result
        printf("The result was: %f\n", result);

        return 0;
}

Regards.
