Capturing latency data with Core Audio - audio

Question

I wrote this code to create an audio file sine.aif using Audio ToolBox framework.
I'm interested in capturing the data latency of this file without running it my phone, just running it on the command line and capturing the time. Is this possible? I do not have much knowledge with Core Audio.
Here is the code:
#import <Foundation/Foundation.h>
#import <AudioToolbox/AudioToolbox.h>
#define SAMPLE_RATE 44100
#define DURATION 5.0
#define FILENAME_FORMAT #"%0.3f-sine.aif"
int main(int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc]init];
if(argc < 2) {
printf("Usage:CAToneFileGenerator 261.526\n");
return -1;
}
double hz = atof(argv[1]);
assert (hz > 0);
NSLog (#"generating %f hz tone", hz);
NSString *fileName = [NSString stringWithFormat:FILENAME_FORMAT, hz];
NSString *filePath = [[[NSFileManager defaultManager]currentDirectoryPath]stringByAppendingPathComponent:fileName];
NSURL *fileURL = [NSURL fileURLWithPath:filePath];
//Prepare the format
AudioStreamBasicDescription asbd;
memset(&asbd, 0, sizeof(asbd));
asbd.mSampleRate = SAMPLE_RATE;
asbd.mFormatID = kAudioFormatLinearPCM;
asbd.mFormatFlags = kAudioFormatFlagIsBigEndian | kAudioFormatFlagIsSignedInteger | kAudioFormatFlagIsPacked;
asbd.mBitsPerChannel = 16;
asbd.mChannelsPerFrame = 1;
asbd.mFramesPerPacket = 1;
asbd.mBytesPerFrame = 2;
asbd.mBytesPerPacket = 2;
//Set up the file
AudioFileID audioFile;
OSStatus audioErr = noErr;
audioErr = AudioFileCreateWithURL((CFURLRef)fileURL, kAudioFileAIFFType, &asbd, kAudioFileFlags_EraseFile, &audioFile);
assert(audioErr == noErr);
//Start writing samples
long maxSampleCount = SAMPLE_RATE * DURATION;
//NSLog (#"maxSampleCount %long", maxSampleCount);
long sampleCount = 0;
UInt32 bytesToWrite = 2;
double wavelengthInSamples = SAMPLE_RATE / hz;
NSLog (#"wavelengthInSamples %f", wavelengthInSamples);
while (sampleCount < maxSampleCount) {
for (int i=0; i < wavelengthInSamples; i++) {
// sine wave
SInt16 sample = CFSwapInt16HostToBig ((SInt16)SHRT_MAX * sin(2 * M_PI * (i / wavelengthInSamples)));
audioErr = AudioFileWriteBytes(audioFile, false, sampleCount*2, &bytesToWrite, &sample);
assert(audioErr == noErr);
sampleCount++;
}
}
audioErr = AudioFileClose(audioFile);
assert(audioErr == noErr);
NSLog (#"wrote %d samples", sampleCount);
[pool drain];
return 0;
}
