Description Andre Klapper 2011-05-30 07:13:32 UTC 
Upstreaming from https://bugs.meego.com/show_bug.cgi?id=14663 .

From http://cgit.freedesktop.org/cairo/tree/util/cairo-trace/trace.c :

777 _init_logfile (void)
778 {
780     const char *filename;
819     filename = getenv ("CAIRO_TRACE_OUTFILE_EXACT");
820     if (filename == NULL) {
821         char buf[4096], name[4096] = "";
834         filename = buf;
837     }
839     logfile = fopen (filename, "wb");

while this is likely to work, there's no requirement that it do so.
