## DESCRIPTION

The MrmRegisterClass function allows MRM to access user-defined widget classes. This function registers the necessary information for MRM to create widgets of this class. You must call MrmRegisterClass prior to fetching any user-defined class widget.

MrmRegisterClass saves the information needed to access the widget creation function and to do type conversion of argument lists by using the information in MRM databases.

`class_name` |  | This argument is ignored; it is present for compatibility with previous releases.
`create_name` |  | Specifies the case-sensitive name of the low-level widget creation function for the class. An example from the Motif Toolkit is XmCreateLabel. Arguments are `parent_widget`, `name`, `override_arglist`, and `override_argcount`. For user-defined widgets, `create_name` is the creation procedure in the UIL that defines this widget.
`create_proc` |  | Specifies the address of the creation function that you named in `create_name`.
`class_record` |  | Specifies a pointer to the class record.
