fchdir
Synopsis
#include <unistd.h>
int fchdir(int fildes);
Status
Declared, not implemented
Conformance
IEEE Std 1003.1-2017
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 offchdir(). -
EIO- An I/O error occurred while reading from or writing to the file system.
