chdir, fchdir - change working directory
Contents
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.
Errors
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).)
EFAULTpath points outside your accessible address space.
EIO An I/O error occurred.
ELOOP Too many symbolic links were encountered in resolving path.
ENAMETOOLONGpath 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.
EBADFfd is not a valid file descriptor.
ENOTDIRfd does not refer to a directory.
History
POSIX.1-2001, SVr4, 4.4BSD.
Library
Standard C library (libc, -lc)
Name
chdir, fchdir - change working directory
Notes
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).
Return Value
On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.
