8.59. DirHandle

Provides methods for accessing Perl's directory functions, avoiding namespace pollution. Creates anonymous glob to hold a directory handle and closes the dirhandle automatically when the last reference goes out of scope. The following methods are provided.

new

$dh = new DirHandle [dirname]

Constructor. Creates a new directory handle. The optional directory name, dirname, defaults to the current directory.

$dh->close(  )

Closes a directory handle; equivalent to the closedir function.

open

$dh->open(dirname)

Opens directory dirname; equivalent to the opendir function.

read

$dh->read(  )

Reads directory entries. Equivalent to the readdir function. In scalar context, reads the next directory entry; in list context, reads all entries.

$dh->rewind(  )

Sets current position to beginning of directory; equivalent to the rewinddir function.
