Section (2) chdir
chdir, fchdir — change working directory
||const char *path
chdir() changes the current
working directory of the calling process to the directory
fchdir() is identical to
chdir(); the only difference is
that the directory is given as an open file descriptor.
On success, zero is returned. On error, −1 is
errno is set
Depending on the filesystem, other errors can be returned.
The more general errors for
chdir() are listed below:
Search permission is denied for one of the components of
path. (See also path_resolution(7).)
pathpoints outside your accessible address space.
An I/O error occurred.
Too many symbolic links were encountered in resolving
pathis too long.
The directory specified in
pathdoes not exist.
Insufficient kernel memory was available.
A component of
pathis not a directory.
The general errors for
fchdir() are listed below:
Search permission was denied on the directory open on
fdis not a valid file descriptor.
fddoes not refer to a directory.
The current working directory is the starting point for interpreting relative pathnames (those not starting with _zsingle_quotesz_/_zsingle_quotesz_).
