i don't exactly understand what you do, do you use GScanner to skip
over a text untill you find a certain keyword/phrase and then read
the text from there with your own routines?
the problem with text is that it always contains a small chunk of the
source text only, so worst case is you just parsed "foo" of "foo bar baz"
and ->text actually only contains "foo ba" (not including trailing \0,
iirc).
gscanner will simply read in more text if it needs to, but for you
->text is basically non-reliable.

what you can do is calling g_scanner_sync_file_offset() after you parsed
"foo", and then read the rest text with read() from gscanner's input fd,
this function will reposition the file pointer to match exactly the position
gscanner is currently parsing at.
(you can also resume scanning at that position at a later point by lseek()ing
the file back to that position and continuing with gscanner as normal).
