Default compare function used if no application specific compare function is specified by the user.
Default compare function used if no application specific compare function is specified by the user.This function compares the values of the pointers directly, i.e. it tests for object identity.
This compare function behaves like the one that can be specified for the C-library function 'qsort'.
The arguments actually passed to the compare function when it is called are addresses of the element pointers added to the list. E.g.: If char * pointers are added to the list, the compare function will be called with char ** pointers as arguments. See the documentation for the C-library function 'qsort' for further information.
