如何确定X11加载的字体名称？

Question

如果我使用以下方法加载字体：

char *fName = (char *)"*-c-60-iso8859-1";
XFontStruct *font = XLoadQueryFont(disp, fName);

它可以是与通配符名称匹配的几种字体中的任何一种。如何确定实际加载的全名？

[编辑] 更正了通配符名称以匹配多个：-c-是-m-哪个不匹配。[结尾]

它是XA_FONT字体的属性。

#include <X11/Xlib.h>
#include <X11/Xatom.h>
#include <stdio.h>
#include <stdlib.h>

int main (int argc, char* argv[])
{
    Display* d = XOpenDisplay(0);
    if (!d)
    {
        fprintf (stderr, "Oops, can't open display\n");
        exit(EXIT_FAILURE);
    }

    while (*++argv)
    {
        XFontStruct* f = XLoadQueryFont(d, *argv);
        unsigned long ret;
        if (f == 0)
            printf ("XLoadQueryFont failed for %s!\n", *argv);
        else
        {
            if (!XGetFontProperty(f, XA_FONT, &ret))
                printf ("XGetFontProperty(%s, XA_FONT) failed!\n", *argv);
            else
                printf ("Full name for %s is %s\n", *argv, XGetAtomName(d, (Atom)ret));
        }
    }
    return 0;
}

跑步：

$ ./prog r14 9x15bold foo
Full name for r14 is -Misc-Fixed-Medium-R-Normal--14-130-75-75-C-70-JISX0201.1976-0
Full name for 9x15bold is -Misc-Fixed-Bold-R-Normal--15-140-75-75-C-90-ISO8859-1
XLoadQueryFont failed for foo!
