Cant understand perror's message with mkdir

Question

I have a piece of code which creates a directory from a string, cwd here is a string giving the directory path. Unfortunately there was an error which didn't allow me to create the directory, so I used the perror() and strerror() functions like so, to get the symbolic name of the error.

struct stat st = {0};
if (stat(cwd, &st) == -1) {

    if(mkdir(cwd, 0700)==-1){
        int err=errno;
        perror("MKDIR ERROR");
        printf("%s \n",strerror(err));
    }

}

My problem is that perror() and strerror() give an error saying 'No such file or directory exists'. I looked up the man page of mkdir here, but the said error is not in the list of errors given on the man page. Am I doing something wrong?

Does the parent directory (ie the directory where you're trying to put your new directory) exist? — Joachim Isaksson, Mar 08 '14 at 11:58
And is cwd a valid path (valid in terms of allowed characters)? — deviantfan, Mar 08 '14 at 11:59

It clearly shows ENOENT which is exactly what you are seeing. Most likely one of the components of your path ("ancestors") does not exist.

I recommend against linux.die.net. I think a better alternative is http://man7.org/linux/man-pages/index.html – cnicutar Mar 08 '14 at 12:00
