Using libsndfile library with C and VS13

[Jony27]

Hi all, I'm trying to get to grips with reading an audio file, printing some info about it and writing it out using the libsndfile library.

This is my first experience with C so I'm not making much progress in terms of understanding.

Anyways, after a quick search on google, I found the code below which does the above, however when I try it, it's not recognising the file.wav and prints out the message.

I have tried placing file.wav inside the project folder and inside the resource folder to no avail.

Could anyone help figure out what I'm doing wrong?

Thanks.

	int i, j;
	FILE *out;

	/* Open the WAV file. */
	info.format = 0;
	sf = sf_open("file.wav", SFM_READ, &info);
	if (sf == NULL)
	{
		printf("Failed to open the file.\n");
		exit(-1);
	}
	/* Print some of the info, and figure out how much data to read. */
	f = info.frames;
	sr = info.samplerate;
	c = info.channels;
	printf("frames=%d\n", f);
	printf("samplerate=%d\n", sr);
	printf("channels=%d\n", c);
	num_items = f*c;
	printf("num_items=%d\n", num_items);

	/* Allocate space for the data to be read, then read it. */
	buf = (int *)malloc(num_items*sizeof(int));
	num = sf_read_int(sf, buf, num_items);
	sf_close(sf);
	printf("Read %d items\n", num);

	/* Write the data to filedata.out. */
	out = fopen("filedata.out", "w");
	for (i = 0; i < num; i += c)
	{
		for (j = 0; j < c; ++j)
			fprintf(out, "%d ", buf[i + j]);
		fprintf(out, "\n");
	}
	fclose(out);
	return 0;
