<command>RD_ListCartCuts</command> is the function to use to list the
fields within a single cart that already exists in the Rivendell Database.
Unlike <command>RD_ListCart</command><manvolnum>7</manvolnum>,
<command>RD_ListCartCuts</command><manvolnum>7</manvolnum> will
also fetch the full list of cuts associated with the requested cart.

(numrecs) and a rd_cart structure which
is stored in the provided memory locations. The rd_cart structure has
the following fields:

<para>
Information about the cuts associated with the cart can be accessed
from the returned rd_cart structure through use of the
<command>RD_ListCartCuts_GetCut()</command> function.
The <parameter>cut_rec</parameter> parameter should range between
<userinput>0</userinput> and one less than the
value of the <parameter>cart_cut_quantity</parameter> member of the
cart's rd_cart structure.
</para>
<para>
Cut information is returned in the form of a rd_cut structure, which
has the following fields:
</para>
