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_codeThis argument is ignored; it is present for compatibility with previous releases. 

class_nameThis argument is ignored; it is present for compatibility with previous releases. 

create_nameSpecifies 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_procSpecifies the address of the creation function that you named in create_name. 

class_recordSpecifies a pointer to the class record. 

RETURN VALUE

This function returns one of these status return constants:

MrmSUCCESSThe function executed successfully. 

MrmFAILUREThe function failed.
