Returns the schema of a database file as an associated array. The key name
|
|
is equal to the field name. Each array element is itself an associated
|
|
array containing the two fields <em>type</em> and
|
|
<em>size</em>. <em>type</em> is one of the constants in
|
|
table <a href="paradox.constants.html#paradox.table-fieldtypes" class="link">Constants for field
|
|
types</a>. <em>size</em> is the number of bytes this field
|
|
consumes in the record. The total of all field sizes is equal to the
|
|
record size as it can be retrieved with <span class="function"><a href="px_get_info.html" class="function">px-get-info()</a></span>.
