Detailed Description

Driver object classes.

Author:

Armin Felke <felke@cs.uni-bonn.de>

The so-called driver objects are used by this library to solve a problem that directly arises from ReChannel's simulation mechanism. Multiple reconfigurable modules accessing one static channel are always a potential source for driver conflicts. In general, driver forwarding is applied if driver identity is required, i.e. the channel's functioning relies on the distinction of process identities.

ReChannel provides driver objects for interface method calls with up to ten arguments. Blocking and non-blocking versions of driver objects are available. A call to a driver object is forwarded to another process that acts as the driver and executes the call.

Remarks:

• Blocking driver objects forward thrown exceptions of type rc_throwable back to the original caller.
• Non-blocking drivers cannot be used for calls that have a return value due to technical reasons. Whereas blocking drivers can forward return values back to the original caller.

Note:

Driver objects are, e.g., required for the use of signal channels together with ReChannel.

See also:

RC_USE_SHARED_METHOD_DRIVER

Remarks:

Define RC_USE_SHARED_METHOD_DRIVER to make all methods use one shared static process. Driver conflicts cannot be detected any more.
