<command>RD_EditCart</command> is the function to use
to edit the fields within a cart that already exists in the Rivendell Database.
</para>
<para>
This function edits a pre-existing cart. User must provide the cart number and any fields which they would like to change. The structure edit_cart_values must be used to tell the API which fields will be changed.

This routine expects an input structure of type edit_cart_values - listed below.
Each field has a boolean flag field (starting with use_) which designates whether
to update the field's value or not. One (1) = true - Use the value in the field or
Zero (0) - Ignore the field.
</para>
<para>
The edit_cart_values structure must be pre-filled with zeroes and has
the following format:
</para>
<programlisting>
struct edit_cart_values {
char cart_grp_name[41];
int use_cart_grp_name;
char cart_title[1021];
int use_cart_title;

</programlisting>
<para>
When successful function will return the number of records sent (numrecs) and a rd_cart structure which
is stored in the provided memory locations. The rd_cart structure has the following fields:
</para>
