139 $Function: ATB_pb_Initialise
140
141 $Description: Initialise an instance of phonebook. Dynamically allocates a record
142 cache in RAM. Creates the necessary file(s) if they do not already exist.
143 Sorts the phonebook by name and by number, creating the appropriate
144 index tables.
145 IMPORTANT: if the file reading is non-blocking - i.e. if a request to read
146 a file does not return with an answer straight away, but the system
147 awaits a callback - then "cache_max" must equal "records_max". This
148 ensures that all records are stored in RAM and can be retrieved without
149 waiting for a response. If the file reading is blocking, then cache_max
150 can be smaller than records_max.
151
152 The memory allocated by this operation will not be freed until
153 ATB_pb_Exit() is called.
154
155 $Returns: PB_OK Action completed OK.

880 name only will be matched; if INDEX_NUMBER, then just the number.
881 The new_log_index parameter should be a pointer to a user allocated
882 integer. This will return the logical index of the closest match in the
883 index list specified. This index either corresponds to a perfect match,
884 or to the record that would appear just after the provided record in the
885 list. For example, if the list consisted of record 0, Alice and record 1,
886 Carol, then a search for Bob would return 1. A search for a record
887 that would occur before the first record always returns 0. A search for
888 a record that would occur after the last record returns the index of the
889 last record +1.
890 The "match" parameter should be a pointer to a user allocated variable
891 of type T_PB_MATCH. This returns information about how closely the
892 found entry matches the record. In the example above, a search for
893 Bob would return 1 and MATCH_NONE; a search for Ca would return 1
