14. File System Interface

This chapter describes the GNU C library's functions for manipulating files. Unlike the input and output functions (see section 12. Input/Output on Streams; see section 13. Low-Level Input/Output), these functions are concerned with operating on the files themselves rather than on their contents.

Among the facilities described in this chapter are functions for examining or modifying directories, functions for renaming and deleting files, and functions for examining and setting file attributes such as access permissions and modification times.

14.3 Working with Directory Trees  Apply actions to all files or a selectable subset of a directory hierarchy.
14.4 Hard Links  Adding alternate names to a file.
14.5 Symbolic Links  A file that "points to" a file name.
14.6 Deleting Files  How to delete a file, and what that means.
14.7 Renaming Files  Changing a file's name.
