Details

This function creates an instance of am_map_t structure, copies all the elements in source_map into the newly created structure and assigns it to map_ptr. It does not alter the contents of source_map.

Memory Concerns: The caller must make sure not to pass a map_ptr which as a valid am_map_t structure, otherwise the reference will be lost. The caller must destroy map_ptr after usage by calling am_map_destroy.
