chdir, fchdir - change working directory
int chdir(const char *path);
int fchdir(int fd);
chdir() changes the current directory to that 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
Depending on the file system, other errors can be returned. The more
general errors for chdir() are listed below:
EACCES Search permission is denied for one of the directories in the
path prefix of path. (See also path_resolution(2).)
EFAULT path points outside your accessible address space.
EIO An I/O error occurred.
ELOOP Too many symbolic links were encountered in resolving path.
path is too long.
ENOENT The file does not exist.
ENOMEM Insufficient kernel memory was available.
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 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).
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
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.
