Manpage of CHDIR

CHDIR

Index
 

NAME

chdir, fchdir - change working directory  

SYNOPSIS

#include <unistd.h>

int chdir(const char *path);
int fchdir(int fd);  

DESCRIPTION

chdir changes the current directory to that specified in path.

fchdir is identical to chdir, 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 chdir are listed below:
EFAULT
path points outside your accessible address space.
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.
EACCES
Search permission is denied on a component of path.
ELOOP
Too many symbolic links were encountered in resolving path.
EIO
An I/O error occurred.

The general errors for fchdir are listed below:

EBADF
fd is not a valid file descriptor.
EACCES
Search permission was denied on the directory open on fd.
 

NOTES

The prototype for fchdir 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 chdir call is compatible with SVr4, SVID, POSIX, X/OPEN, 4.4BSD. SVr4 documents additional EINTR, ENOLINK, and EMULTIHOP error conditions but has no ENOMEM. POSIX.1 does not have ENOMEM or ELOOP error conditions. X/OPEN does not have EFAULT, ENOMEM or EIO error conditions.

The fchdir 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.
