    Description

    OnKeyPtrCompare is used to compare the values of 2 keys. By default it simply compares the byte values of the key memory block. It can be set to any function that performs another comparison. (e.g. a function that treats the memory blocks as a string pointer and compare the actual strings).

    This function is used to find a data item (IndexOf).
