File system readdir
// INCLUDE #include <dirent.h> // PROTOTYPE struct dirent* readdir(DIR* dirp)
Reads the next entry from a directory. Used to find the names of all of the files and directories within a directory. See also
Returns a pointer to a
struct dirent containing information about the next file in the directory. Returns NULL when the end of the directory is reached. Returns NULL and sets
errno if an error occurs.
Not all fields of the
struct dirent are filled in. You should only rely on:
d_type: Type of entry:
d_name: Name of the file or directory. Just the name, not the whole path.
This structure is reused on subsequent calls to
readdir so if you need to save the values, you'll need to copy them.
