Hello,
First of all, sorry if this is not the adecuate list to ask about
GLib, but I haven't found the list about GLib.
I'm newbie with GLib and I have some problems about memory leaks. I'm
testing the simple code:
#include<glib.h>
int main(){
GPtrArray* dataArray=g_ptr_array_new();
g_ptr_array_free(dataArray,TRUE);
return 0;
}
I only initialize and free one GPtrArray object.
if I compile it and run with valgrind (http://valgrind.org/) I obtain:
gcc -g -Wall -Wextra -I/usr/include/glib-2.0
-I/usr/lib/glib-2.0/include memptr.c -o memptr -lgts
valgrind --leak-check=full ./memptr

Valgrind says that some memory were lost (possibly lost and still
reachable). Is this behaviour known? Is it a bug? What is the correct
way fot free GPtrArray?
