A hack:

#include <stdio.h>
int main (int argc, char ** argv)
	{
	FILE * infile;
	char buf[128];

	sprintf (buf, "dir %s > delete.me\n", argv[1]);
	system (buf);
	if ((infile = fopen ("delete.me", "r")) == NULL)
		{
		printf ("oops\n");
		exit (0);
		}
	while (1)
		{
		if (fgets (buf, sizeof (buf), infile) != buf)
			{
			break;
			}
		if (strstr (buf, "Volume in drive") != NULL)
			{
			printf ("%s\n", buf);
			break;
			}
		}
	fclose (infile);
	unlink ("delete.me");
	}
