NAME

       PX_put_recordn — Stores record in Paradox file at certain position

SYNOPSIS

       #include <paradox.h>

       int PX_put_recordn(pxdoc_t *pxdoc, char *data, int recpos)

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 H records and the first call of PX_put_recordn wants to store  a  record
       at  position  11,  then  this will be corrected to position H. 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.
