Function that finds the absolute path of a file

Question

Hi,
I'm creating an application using the SDL framework.
The following code gives me the absolute path for the file "caisse.jpg", which is located in my application bundle. Then, I can use the value of "cstrURL" to load the image with IMG_Load(cstrURL);
#import <CoreFoundation/CoreFoundation.h>
int main(int argc, char *argv[])
CFURLRef url = CFBundleCopyResourceURL( CFBundleGetMainBundle(),
CFSTR("caisse"),
CFSTR("jpg"), //extension du fichier
NULL );
const char* cstrURL = CFStringGetCStringPtr(
CFURLCopyFileSystemPath(url,kCFURLPOSIXPathStyle),
CFStringGetSystemEncoding()
printf("URL: %s", cstrURL);
return EXIT_SUCCESS;
But I have many files to load for my application. I tried to create a function that would take as parameter informations about the image, and then automatically find the absolute path of this image.
( void imgPath(char name[], char ext[], char destination[] ---> name = "image", ext = "jpg", destination is a variable in which the function puts the absolute path of the file)
How can I do that? What bugs me is the use of the CFSTR macro in the code I have...
Thank you very much

The CFSTR macro can only use a constant string as parameter, not a variable one.
You can use instead CFStringCreateWithCString if the parameter is a C String (char *).
Additionaly, I think the input parameters of your imgPath function must be of char* type, not char. And the output parameter char** (but it would be easier to know with the function source code).
