PX_PUT_RECORDN
DESCRIPTION
Stores a record in the buffer data into a
Paradox file at the given position recpos.
The first position has number 0. The function will determine the
data block for this record. If the position is after the last data
block, then as many as needed empty data blocks will be added.
If the position is in the middle of a data block and there is
no record right before the position, then the position will be
recalculated to make sure the new record will be stored in the
first free slot of the datablock. For example, if a datablock contains
10 records and the first call of PX_put_recordn wants
to store a record at postion 11, then this will be corrected to position
10. PX_put_recordn will also add an empty data block
and store the record as the first record of the second data block.
Storing a second record at position 11 again, will be executed
without any position change.
data must be constructed with PX_put_data_xxx(3)
functions before. It is of the same structure as the record returned
by PX_get_record(3) and PX_get_record2(3).
RETURN VALUE
Returns the record position on success and -1 on failure. The first position has number 0.
