   fchdir    ( 2 )

сменить рабочий каталог (change working directory)

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).
