Checking if a file is a directory or just a file.
- by Jookia
I'm writing a program to check if something is a file or is a directory. Is there a better way to do it than this?
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>
#include <errno.h>
int isFile(const char* name)
{
DIR* directory = opendir(name);
if(directory != NULL)
{
closedir(directory);
return 0;
}
if(errno == ENOTDIR)
{
return 1;
}
return -1;
}
int main(void)
{
const char* file = "./testFile";
const char* directory = "./";
printf("Is %s a file? %s.\n", file,
((isFile(file) == 1) ? "Yes" : "No"));
printf("Is %s a directory? %s.\n", directory,
((isFile(directory) == 0) ? "Yes" : "No"));
return 0;
}
