fchdir():

chdir() changes
the current working directory of the calling process to the directory specified
in path.
fchdir() is identical to chdir(); the only difference is that the
directory is given as an open file descriptor.
On success, zero
is returned. On error, -1 is returned, and errno is set appropriately.
Depending
on the filesystem, other errors can be returned. The more general errors
for chdir() are listed below:
- EACCES
- Search permission is denied for one
of the components of path. (See also path_resolution(7)
.)
- EFAULT
- path points
outside your accessible address space.
- EIO
- An I/O error occurred.
- ELOOP
- Too
many symbolic links were encountered in resolving path.
- ENAMETOOLONG
- path
is too long.
- ENOENT
- The file does not exist.
- ENOMEM
- Insufficient kernel memory
was available.
- ENOTDIR
- A component of path is not a directory.
The general
errors for fchdir() are listed below:
- EACCES
- Search permission was denied
on the directory open on fd.
- EBADF
- fd is not a valid file descriptor.

The current working directory is the starting
point for interpreting relative pathnames (those not starting with aq/aq).
A child process created via fork(2)
inherits its parent’s current working
directory. The current working directory is left unchanged by execve(2)
.
