<DT><B> Synopsis </B><DD><P>Allocate a class for a new data type
<DT><B> Usage </B><DD><P><CODE>SLang_Class_Type *SLclass_allocate_class (char *name)</CODE>
<DT><B> Description </B><DD><P>The purpose of this function is to allocate and initialize space
that defines a new data type or class called <CODE>name</CODE>.  If
successful, a pointer to the class is returned, or upon failure the
function returns <CODE>NULL</CODE>.
<P>This function does not automatically create the new data type.
Callback functions must first be associated with the data type via
functions such as <CODE>SLclass_set_push_function</CODE>, and the the data
type must be registered with the interpreter via
<CODE>SLclass_register_class</CODE>.  See the <B>S-lang</B> library programmer's
guide for more information.
