This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the corresponding
Linux manual page for details of Linux behavior), or the interface may
not be implemented on Linux.
NAMEfchdir - change working directory
int fchdir(int fildes);
The fchdir() function shall be equivalent to chdir() except that the
directory that is to be the new current working directory is specified
by the file descriptor fildes.
A conforming application can obtain a file descriptor for a file of
type directory using open(), provided that the file status flags and
access modes do not contain O_WRONLY or O_RDWR.
Upon successful completion, fchdir() shall return 0. Otherwise, it
shall return -1 and set errno to indicate the error. On failure the
current working directory shall remain unchanged.
The fchdir() function shall fail if:
EACCES Search permission is denied for the directory referenced by
EBADF The fildes argument is not an open file descriptor.
The open file descriptor fildes does not refer to a directory.
The fchdir() may fail if:
EINTR A signal was caught during the execution of fchdir().
EIO An I/O error occurred while reading from or writing to the file
