<para>
After calling <function>sesam_query</function> with a "select
type" query, this function gives you the number of columns in the
result. Returns an integer describing the total number of
columns (aka. fields) in the current
<parameter>result_id</parameter> result set or
&false; on error.
</para>
<para>
For "immediate" statements, the value zero is returned. The SESAM
"multiple field" columns count as their respective dimension,
i.e., a three-column "multiple field" counts as three columns.
</para>
<para>
See also: <function>sesam_query</function> and
<function>sesam_field_array</function> for a way to distinguish
between "multiple field" columns and regular columns.
