Hello,
I have tested XLoadFont with parameter "-*-*-*-*-*-*-*-*-*-*-*-*-iso8859-1"
and it worked. My version of Xfree86 is "4.1.0 from 2 June 2001".
A quick look at the implementation revealed that XLoadFont always returns
a valid resource id. But XLoadQueryFont returns 0 in case of an error
my be you want to use this function instead of XLoadFont.
To get to font name of a loaded font use the following code snippet
unsigned long aFontname = None ;
XFontStruct* pXfont = 0 ;
pXfont = XLoadQueryFont(display,"-*-*-*-*-*-*-*-*-*-*-*-*-iso8859-1" ) ;
/*
or use
pFfont = XQueryFont( display, font ) ;
if you want to use XLoadFont
*/
if (pXfont && XGetFontProperrty( pXfont, XA_FONT, &aFontname ))
{
char* strFontName = 0 ;
strFontName = XGetAtomName( display, aFontName ) ;
/* use name here */
/* ... */
XFree( strFontName ) ; strFontName = 0 ;
}
if (pXfont) XFreeFont( display, pXfont) ; pXfont = 0 ;
