Create a new paradox database file. The actual file has to be opened before
|
|
with <function>fopen</function>. Make sure the file is writable. The first
|
|
parameter is the return value of <function>px_new</function>.
|
|
<option>fielddesc</option> is an array containing one element for each
|
|
field specification. A field specification is an array
|
|
itself with either two or three elements.The first element is always a
|
|
string value used as the name of the field. It may not be larger than ten
|
|
characters. The second element contains the field type which is one of the
|
|
constants listed in the table
|
|
<link linkend="paradox.table-fieldtypes">Constants for field types</link>.
|
|
In the case of a character field or bcd field, you will have to provide a
|
|
third element
|
|
specifying the length respectively the precesion of the field.

<para>Calling this functions issues a warning about an empty tablename which
|
|
can be savely ignored. Just set the tablename afterwards with
|
|
<function>px_set_parameter</function>.</para>

|
|
<note>
|
|
<para>This function is highly experimental, due to insufficient
|
|
documentation of the paradox file format. Database files created with this
|
|
function can be opened by <function>px_open_fp</function> and has been
|
|
successfully opened by the Paradox software, but your milage may vary.
