Hi,
Yes, i am able to see many errors related to FcFontMatch in
valgrind..FcPatternDestroy() function is called after FcFontMatch() in my
code below is the function......
FcPattern* match = FcFontMatch(0, pattern, &result);
if(match) {
FcChar8* str = 0;
if(FcPatternGetString(match, FC_FILE, 0, &str) ==
FcResultMatch) {
filename = (const char*)str;
}
}
FcPatternDestroy(pattern);
}
printf("return from FontConfig::Find\n");
return filename;
}
And in valgrind other FcFontMatch related errors are--------
