char *mi_class_name(VPclass_id)
   mi_integer VPclass_id;

VPclass_id

is a VP-class identifier for the VP class whose name the function is to return. This argument can be either of the following values:

A valid VP-class identifier

Obtains the name of the specified VP class.

MI_CURRENT_CLASS
VP-class constant

Obtains the name of the VP class of the current VP.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
No	Yes

The mi_class_name( ) function obtains the name of the VP class that VPclass_id specifies. The VP-class name is assigned to the VP class in the VPCLASS configuration parameter. For example, suppose you have the following VPCLASS configuration parameter:

VPCLASS=newvp, num=3, max=6

The mi_class_name( ) function returns the string 'newvp' when it receives the VP-class identifier for the newvp VP class. You can obtain a VP-class identifier with the mi_vpinfo_classid( ) or mi_class_id( ) function.

A char pointer

is a pointer to the name of the VP class associated with the specified VP-class identifier.

NULL

indicates that the function was not successful.

See also the descriptions of mi_class_id( ), mi_class_maxvps( ), mi_class_numvp( ), and mi_vpinfo_classid( )).
