Имя (Name)
chdir, fchdir - change working directory
Синопсис (Synopsis)
#include <unistd.h>
int chdir(const char *path);
int fchdir(int fd);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
fchdir():
_XOPEN_SOURCE >= 500
|| /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L
|| /* Glibc up to and including 2.19: */ _BSD_SOURCE
Описание (Description)
chdir() changes the current working directory of the calling
process to the directory specified in path.
fchdir() is identical to chdir(); the only difference is that the
directory is given as an open file descriptor.
Возвращаемое значение (Return value)
On success, zero is returned. On error, -1 is returned, and
errno is set to indicate the error.
Ошибки (Error)
Depending on the filesystem, other errors can be returned. The
more general errors for chdir() are listed below:
EACCES Search permission is denied for one of the components of
path. (See also path_resolution(7).)
EFAULT path points outside your accessible address space.
EIO An I/O error occurred.
ELOOP Too many symbolic links were encountered in resolving
path.
ENAMETOOLONG
path is too long.
ENOENT The directory specified in path does not exist.
ENOMEM Insufficient kernel memory was available.
ENOTDIR
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.
ENOTDIR
fd does not refer to a directory.
Стандарты (Conforming to)
POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD.
Примечание (Note)
The current working directory is the starting point for
interpreting relative pathnames (those not starting with '/').
A child process created via fork(2) inherits its parent's current
working directory. The current working directory is left
unchanged by execve(2).
