This is an old thread, but it deals with something I'm wondering
about...

Does this clear out the data from memory, though? I used this same
techique as shown above, but From the output of "memprof", I am doubting
it. What I've come up with (and I think memprof shows an improvement)
is: (freehand typing and generalization - may be typos)
------------------------ cut --------------------
GString *str; /* global */
gchar *strpt; /* auto */
if( <data in buffer> ) {
<above routine to null out the buffer>
g_string_free(str,TRUE); /* New addition */
}
while reading data from file
g_string_append(str, filebuffer);
strpt = str->str;
/* g_string_free(strpt,FALSE)*/ << commented out now, want to save for
next buffer load>>
gtk_text_buffer_set_text (textbuffer, strpt, -1);
/* I think I could eliminate "strpt" altogether now, and in the previous
* line, substitute str->str for strpt, right? */
----------------
Question is: Am I correct here? Is all this above code needed? As I
said above, memprof _shows_ cleaner memory with the additional
g_string_free(str...), but is memprof accurate for all things like this?
