66This module provides access to the IRIS <em>Font Manager</em> library.
67<a id='l2h-5190' xml:id='l2h-5190'></a>
68It is available only on Silicon Graphics machines.
69See also: <em>4Sight User's Guide</em>, section 1, chapter 5: ``Using
70the IRIS Font Manager.''
71
72<P>
73This is not yet a full interface to the IRIS Font Manager.
74Among the unsupported features are: matrix operations; cache
75operations; character operations (use string operations instead); some
76details of font info; individual glyph metrics; and printer matching.
77

85<dd>
86Initialization function.
87Calls <tt class="cfunction">fminit()</tt>.
