.PP 
Enhanced Metafile Header Record\&. 

The \fBENHMETAHEADER\fP serves two purposes in this library: it keeps track of the size of the metafile (in physical dimensions) and number of records and handles that are ultimately to be written to the disk file\&. It is also a real record that must be written out\&.

.PP
\fBParameters:\fP
.RS 4
\fIdescription\fP an optional description argument is a UNICODE-like string with the following format: 'some text\\0some more text\\0\\0'\&. The W32 interface defines UNICODE characters to be two-byte (unsigned short strings)\&. The constructor makes a copy of the argument\&.
