int fchdir(int fd);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

DESCRIPTIONchdir() changes the current working directory of the calling process to the directory specified in path.
RETURN VALUEOn success, zero is returned. On error, -1 is returned, and errno is set appropriately.
ERRORSDepending on the filesystem, other errors can be returned. The more general errors for chdir() are listed below:
- Search permission is denied for one of the components of path. (See also path_resolution(7).)
- path points outside your accessible address space.
- An I/O error occurred.
- Too many symbolic links were encountered in resolving path.
- path is too long.
- The directory specified in path does not exist.
- Insufficient kernel memory was available.
- A component of path is not a directory.
The general errors for fchdir() are listed below:
- Search permission was denied on the directory open on fd.
- fd is not a valid file descriptor.
CONFORMING TOPOSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD.
NOTESThe current working directory is the starting point for interpreting relative pathnames (those not starting with '/').
