As discussed in section Identities , application-specific identity types can be registered with the ILU kernel for use with various authorization and accounting schemes, and to support various forms of security in wire protocols and transports. After this is done, values of the new identity types may be used. Note that the mere act of registering a new identity type with the ILU kernel will not cause values of that identity type to be automatically transmitted in ILU calls. This will only happen if an appropriately designed transport or protocol, which knows to do this, is also used. For experimental purposes, we provide a switch will will cause the various flavors of Sun RPC implemented for ILU to automatically pass one specific identity type.
Applications can register callback functions to handle malloc failures, in two ways.
The ILU kernel contains a large number of debugging print statements, which document various things going on inside the kernel. The file will be created, and debugging messages will be written to it. Go to the previous , next section.
