Just my 2 cents although they might be on another currency... How about
using a GSList (gtk single list) with GStrings??? So you won't have to
worry about the size of neither the list or of any array... If you still
want to use an array I am sure I have read somewhere in my textbook that
there is a dynamic way of defining it (or declare it... never understood
the difference). If I recall even better you have to scan the dir once
to get the number of elements, declare your array, rescan to get the
actual contents and then you can do even more dynamic mallocation if you
use another gchar[] to hold each of the values... OK, it does not even
make sense to me... in pseudocode:
gint filesNum=0;
scan directory and count the files in filesNum;
gchar *array[filesNum];
gchar buf[512]; //if you really "hate" GString
gint i=0;
while (!end of files in the dir)
{
read filename to buf;
*array[i] = (gint) malloc(sizeof(gchar)*length_of_str(buf)); //this
probably is wrong, but I am sure you can figure it out with a good
textbook or some examples on *argv[]
strcpy(*array[i], buf);
}
BTW someone posted:
gchar *myArray = g_malloc (sizeof (gchar) * 20 * 512);
which is only a string and not an array of strings so what you basically
do is just define a 20 times your default string length character long
string...
Having said all that I still think that a GSList* of GStrings* would be
much easier...
