find directory in a C program

Question

How can I find if a directory exists or not in a C program? I know that getcwd() gives you the current directory but I want to find ANY directory. Is there a function for that or how do I do it? I am using Ubuntu

This might be of help? http://stackoverflow.com/questions/9314586/c-faster-way-to-check-if-a-directory-exists — Kevin Brydon, May 22 '13 at 08:26
`man opendir`, `man stat` (of course, if you are using UNIX-based OS). — Eddy_Em, May 22 '13 at 08:29

opendir, readdir and closedir are POSIX functions, so they should be available in Linux, MacOS, Windows as well as any Unix type system.

you can use access() function , like for example:

access(path, F_OK);

It returns 0 if found. -1 if not found.

int mkdir (const char *filename, mode_t mode)

you need to include the header file sys/stat.h to use this function.

The mkdir function creates a new, empty directory with name filename. The argument mode specifies the file permissions for the new directory file.A return value of 0 indicates successful completion, and -1 indicates failure.

In case of failure and if your Directory already exists errno value will equal to EEXIST.
