How to create directories using the C standard library (or otherwise) ?

Question

Help appreciated. Couldn't find any mention of this in "the book" (k&r).

Answer 1

By calling the mkdir() function. That links to the manual page online. To get that page on your (Linux) machine, enter in a terminal:

$ man 2 mkdir

The '2' is important, and is called the manual page section number. Since you want help for the C function "mkdir", as opposed to the command-line command "mkdir", you need to specify the section as otherwise you will get the command by default.

Answer 2

On Linux, you can use the POSIX mkdir().

For documentation, click that link or try man 2 mkdir from the command line.

Answer 3

mkdir

Answer 4

Although not part of the standard library, most implementations do include mkdir():

#include <dir.h>
...
mkdir("directory");
