<p>Type of font to be used by the FLT driver. </p>
<p>The type <a class="el" href="structMFLTFont.html" title="Type of font to be used by the FLT driver.">MFLTFont</a> is the structure that contains information about a font used by the FLT driver. Usually, an application should prepare a bigger structure whose first element is <a class="el" href="structMFLTFont.html" title="Type of font to be used by the FLT driver.">MFLTFont</a> and has more information about the font that is used by callback funcitons, and give that structure to mflt functions by coercing it to <a class="el" href="structMFLTFont.html" title="Type of font to be used by the FLT driver.">MFLTFont</a>. It is assured that callback functions can safely coerce <a class="el" href="structMFLTFont.html" title="Type of font to be used by the FLT driver.">MFLTFont</a> back to the original structure. </p>
