NAME

fchdir — change working directory

SYNOPSIS

#include <unistd.h>

int fchdir(int fildes);


DESCRIPTION

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.

RETURN VALUE

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.

ERRORS

The fchdir() function shall fail if:

[EACCES]

Search permission is denied for the directory referenced by fildes.

[EBADF]

The fildes argument is not an open file descriptor.

[ENOTDIR]

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 system.
