All Compact Libraries
All compact ISI libraries support all features detailed under IsiFull , except those
specifically excluded in the description of the particular version of compact ISI
library. The following features are also not supported by compact ISI libraries:
• Direct removal or replacement of existing network variable connections is
not supported. Connection invitations will be ignored for assemblies that
are already in a connection. The IsiLeaveEnrollment() and
IsiDeleteEnrollment() functions are not present. To remove an existing
connection from a device that uses a compact ISI library, call the
IsiReturnToFactoryDefaults() function to return the device to the factory
defaults. To replace an existing connection on such a device, return the
device to the factory defaults, and then create the new connection.
• Network variable turnaround connections are not supported with the
compact libraries.
• The compact libraries require support by the application to pre-validate
resources prior to enrolling with a new connection, whereas the IsiFull
library contains more comprehensive, built-in, support for this validation.
See the IsiGetFreeAliasCount() function for more information.
• Diagnostics are not supported; the isiFlagSupplyDiagnostics flag is ignored.
The following table compares the features of each library.
