struct mach_task_basic_info info;
mach_msg_type_number_t size = MACH_TASK_BASIC_INFO_COUNT;
kern_return_t kerr = task_info(mach_task_self(),
                               MACH_TASK_BASIC_INFO,
                               (task_info_t)&info,
                               &size);
if( kerr == KERN_SUCCESS ) {
    NSLog(@"Memory in use (in bytes): %u", info.resident_size);
    return info.resident_size;
} else {
    NSLog(@"Error with task_info(): %s", mach_error_string(kerr));
}
