Возвращаемые значения

Returns an associated array with lots of information about a paradox file. This array is likely to be extended in the future.

fileversion -

Version of file multiplied by 10, e.g. 70.

Name of table as stored in the file. If the database was created by pxlib, then this will be the name of the file without the extension.

numrecords -

Number of records in this table.

numfields -

Number of fields in this table.

headersize -

Number of bytes used for the header. This is usually 0x800.

recordsize -

Number of bytes used for each record. This is the sum of all field sizes (available since version 1.4.2).

maxtablesize -

This value multiplied by 0x400 is the size of a data block in bytes. The maximum number of records in a datablock is the integer part of (maxtablesize * 0x400 - 8) / recordsize.

numdatablocks -

The number of data blocks in the file. Each data block contains a certain number of records which depends on the record size and the data block size (maxtablesize). Data blocks may not necessarily be completely filled.

numindexfields -

Number of fields used for the primary index. The fields do always start with field number 1.

codepage -

The DOS codepage which was used for encoding fields with character data. If the target encoding is not set with px_set_targetencoding() this will be the encoding for character fields when records are being accessed with px_get_record() or px_retrieve_record().
