SYNOPSIS

#include <unistd.h> int chdir(const char * path ); int fchdir(int fd );

chdir changes the current directory to that specified in path .

fchdir is identical to chdir , only that the directory is given as an open file descriptor.

Depending on the file system, other errors can be returned. The more general errors for chdir are listed below:

EFAULT

CONFORMING TO

The chdir call is compatible with SVr4, SVID, POSIX, X/OPEN, 4.4BSD. SVr4 documents additional EINTR, ENOLINK, and EMULTIHOP error conditions but has no ENOMEM. POSIX.1 does not have ENOMEM or ELOOP error conditions. X/OPEN does not have EFAULT, ENOMEM or EIO error conditions.

The fchdir call is compatible with SVr4, 4.4BSD and X/OPEN. SVr4 documents additional EIO, EINTR, and ENOLINK error conditions. X/OPEN documents additional EINTR and EIO error conditions.
