TBLT_RETC TBLT_ENTRY BltDataCloseFile(TBLT_DH *dhPtr);


 dhPtr          IO:data file control structure

This routine closes a DBF data file that was opened by BltDataOpenFile(), and if its .memoHandle indicates a memo file, the memo file is also closed.

Any file that has been written to must be closed by calling this routine before ending your program. If the data structure at dhPtr is no longer required, you should release the memory after a successful close.

This routine should be called for every open file handle opened by BltDataOpenFile() regardless of exit conditions. It's recommened that an exit handler be installed and for it to verify that all handles opened are closed before exiting your program.

Return: Non-zero indicates an error, otherwise the file's DBF (and DBT) header was updated and the handle closed.
