Wrap your C functions in Objective-C methods.
For example:
SomeController.m
#import "libwhatever.h"
@implementation SomeController
+ (void)initializeLibrary
{
InititaliseCLibrary();
}
- (BOOL)writeToURL:(NSURL *)url
{
char path[255];
//convert URL to C string using NSURL/CFURL API here
//call C library
int result = WriteFileToPath(...);
//return a value
return (result == 0 ? YES : NO);
}
....and so on. This is the exact same way parts of Carbon and CoreFoundation is
used in an Objective-C based application.
