#include <dirent.h>
#include <errno.h>
int main(int argc, char *argv[])
{
		DIR			 *dip;
		struct dirent   *dit;
		int			 i = 0;
		/* check to see if user entered a directory name */
		if (argc < 2)
		{
				printf("Usage: %s <directory>\n", argv[0]);
				return 0;
		}
		/* DIR *opendir(const char *name);
		 *
		 * Open a directory stream to argv[1] and make sure
		 * it's a readable and valid (directory) */
		if ((dip = opendir(argv[1])) == NULL)
		{
				perror("opendir");
				return 0;
		}
		printf("Directory stream is now open\n");
		/*  struct dirent *readdir(DIR *dir);
		 *
		 * Read in the files from argv[1] and print */
		while ((dit = readdir(dip)) != NULL)
		{
				i++;
				printf("\n%s", dit->d_name);
		}
		printf("\n\nreaddir() found a total of %i files\n", i);
		/* int closedir(DIR *dir);
		 *
		 * Close the stream to argv[1]. And check for errors. */
		if (closedir(dip) == -1)
		{
				perror("closedir");
				return 0;
		}
		printf("\nDirectory stream is now closed\n");
