NAME
DirHandle - supply object methods for directory handlesSYNOPSIS
use DirHandle;
$d = new DirHandle ".";
if (defined $d) {
while (defined($_ = $d->read)) { something($_); }
$d->rewind;
while (defined($_ = $d->read)) { something_else($_); }
undef $d;
}
DESCRIPTION
The "DirHandle" method provide an alternative interface to the opendir(), closedir(), readdir(), and rewinddir() functions.The only objective benefit to using "DirHandle" is that it avoids namespace pollution by creating globs to hold directory handles.
NOTES
- *
-
On Mac OS (Classic), the path separator is ':', not '/', and the
current directory is denoted as ':', not '.'. You should be careful
about specifying relative pathnames. While a full path always begins
with a volume name, a relative pathname should always begin with a
':'. If specifying a volume name only, a trailing ':' is required.
