NAME

       XBase::Memo - Generic support for various memo formats

SYNOPSIS

       Used indirectly, via XBase. Users should check its man page.

DESCRIPTION

       Objects of this class are created to deal with memo files, currently .dbt, .fpt and .smt (code for this provided by Dirk Tostmann).
       Package XBase::Memo defines methods read_header to parse that header of the file and set object's structures, write_record and last_record
       to write the records properly formated and find the end of file.

       There are four separate subpackages in XBase::Memo, dBaseIII, dBaseIV, Fox and Apollo. Memo objects are effectively of one of these types
       and they override their specific record handling routines where appropriate.

NAME

       XBase::Base - Base input output module for XBase suite

SYNOPSIS

       Used indirectly, via XBase or XBase::Memo.

DESCRIPTION

       This module provides catch-all I/O methods for other XBase classes, should be used by people creating additional XBase classes/methods.
       There is nothing interesting in here for users of the XBase(3) module.  Methods in XBase::Base return nothing (undef) on error and the
       error message can be retrieved using the errstr method.

       Methods are:

       new Constructor. Creates the object and if the file name is specified, opens the file.

       open
	   Opens the file and using method read_header reads the header and sets the object's data structure. The read_header should be defined in
	   the derived class, there is no default.

       close
	   Closes the file, doesn't destroy the object.

       drop
	   Unlinks the file.

       create_file
	   Creates file of given name. Second (optional) paramater is the permission specification for the file.

       The reading/writing methods assume that the file has got header of length header_len bytes (possibly 0) and then records of length
       record_len. These two values should be set by the read_header method.

       seek_to, seek_to_record
	   Seeks to absolute position or to the start of the record.

       read_record, read_from
	   Reads data from specified position (offset) or from the given record.  The second parameter (optional for read_record) is the length to
	   read. It can be negative, and at that case the read will not complain if the file is shorter than requested.

       write_to, write_record
	   Writes data to the absolute position or to specified record position.  The data is not padded to record_len, just written out.

       General locking methods are locksh, lockex and unlock, they call _locksh, _lockex and _unlock which can be redefined to allow any way for
       locking (not only the default flock). The user is responsible for calling the lock if he needs it.

       No more description -- check the source code if you need to know more.
