Get NSHomeDirectory() in pure C

Question

I am trying to get the NSHomeDirectory() in pure C

#include <CoreFoundation/CFBundle.h>
#include <CoreFoundation/CoreFoundation.h>

void testFunc() {
    printf(NSHomeDirectory()); 
}

Answer 1

You need to send the UTF8String message to the NSString object returned by NSHomeDirectory() to obtain a C string. To do this in pure C (Tested):

#include <objc/runtime.h>
#include <objc/message.h>
void *NSHomeDirectory();
void testFunc() {
    puts(((const char *(*)(void *, SEL))objc_msgSend)(NSHomeDirectory(), sel_getUid("UTF8String")));
    // Also use puts() instead of printf() here
}

Note: Compile using -framework Cocoa
