Имя (Name)
fchdir — change working directory
Синопсис (Synopsis)
#include <unistd.h>
int fchdir(int fildes);
Описание (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.
Возвращаемое значение (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.
Ошибки (Error)
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.
