They're definitely not equivalent. Specifically: > If varA is defined as a const gchar *, will the program automatically free the > memory allocated with g_strdup ?
No. If you use strdup (or malloc, etc.), you need to free the resulting pointer afterwards. const on a pointer just means that you shouldn't modify the memory that the pointer points to. This is more useful when you use string constants. In C, this isn't strictly enforced, but in C++ it is. See also http://publications.gbdirect.co.uk/c_book/chapter8/const_and_volatile.html .
