#include <sys/stat.h>
#include <sys/types.h>
int mkdir(const char *pathname, mode_t mode);

With the advent of c++17 we have a Filesystem library providing facilities for manipulating files and directory. To create a directory, you can use std::filesystem::create_directory.

Example:

#include <filesystem>
std::filesystem::create_directory("newdir");

Answer 3

If you can use C++ (as suggested by the selected tags) and boost libraries, Boost filesystem can help you with the create_directory function.

If you don't want to have all boost libraries available in your project, you may download a tool called bcp to extract only the subset you need, in your case boost filesystem and its dependencies.

Answer 4

Call mkdir(2).
