chdir

chdir(2)							System Calls Manual							  chdir(2)

NAME

       chdir, fchdir - change working directory

SYNOPSIS

DESCRIPTION

       and  cause  a  directory pointed to by path or fildes to become the current working directory, the starting point for path searches of path
       names not beginning with path points to the path name of a directory.  fildes is an open file descriptor of a directory.

       For a directory to become the current working directory, a process must have execute (search) access to the directory.

RETURN VALUE

       Upon successful completion, a value of 0 is returned.  Otherwise, a value of -1 is returned and is set to indicate the error.

ERRORS

       fails and the current working directory remains unchanged if one or more of the following are true:

	      A component of the path name is not a directory.

	      The named directory does not exist.

	      Search permission is denied for any component of the path name.

	      path		    points outside the allocated address space of the process.	The reliable detection of this error is  implemen-
				    tation dependent.

	      path		    is null.

	      The length of the specified path name exceeds
				    bytes, or the length of a component of the path name exceeds bytes while is in effect.

	      Too many symbolic links were encountered in translating the path name.

       fails and the current working directory remains unchanged if one or more of the following are true:

	      Search permission is denied for
				    fildes.

	      fildes		    is not an open file descriptor.

	      The open file descriptor
				    fildes does not refer to a directory.
