NAME

fchdir - change working directory

SYNOPSIS

#include <unistd.h>

int fchdir(int fd);

DESCRIPTION

fchdir is identical to chdir(2), only that the directory is given as an open file descriptor.

RETURN VALUE

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.

ERRORS

Depending on the file system, other errors can be returned. The more general errors for fchdir(2) are listed below:

ENOENT

The file does not exist.

ENOMEM

Insufficient kernel memory was available.

EIO

An I/O error occurred.

EBADF

fd is not a valid file descriptor.

EACCES

Search permission was denied on the directory open on fd.

NOTES

The prototype for fchdir(2) is only available if _BSD_SOURCE is defined (either explicitly, or implicitly, by not defining _POSIX_SOURCE or compiling with the -ansi flag).

CONFORMING TO

The fchdir(2) call is compatible with SVr4, 4.4BSD and X/OPEN. SVr4 documents additional EIO, EINTR, and ENOLINK error conditions. X/OPEN documents additional EINTR and EIO error conditions.
