Creating a new directory in C

c, directory, linux

Solution

Look at `stat` for checking if the directory exists,

And `mkdir`, to create a directory.

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

struct stat st = {0};

if (stat("/some/directory", &st) == -1) {
    mkdir("/some/directory", 0700);
}

You can see the manual of these functions with the `man 2 stat` and `man 2 mkdir` commands.

Problem

I want to write a program that checks for the existence of a directory; if that directory does not exist then it creates the directory and a log file inside of it, but if the directory already exists, then it just creates a new log file in that folder. How would I do this in C with Linux?
