fchdir - change working directory
Návod, kniha: POSIX Programmer's Manual
#include <unistd.h>
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
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.
