This package provides an Ada interface to a communication network. The model of the network is one that allows tasks on separate nodes to pass messages (message-passing). The package is designed to be similar to the standard package SEQUENTIAL_IO, with the same basic operations, applicable to networks. The idea of SEQUENTIAL_IO (just as for the other predefined I/O packages) is machine independent logical operations defined in the spec, and machine dependencies hidden in the private parts and the bodies. Currently NETWORK_IO allows any typed link to be created between two VAX DECnet nodes. Dependent Units : STARLET, CONDITION_HANDLING, TASKING_SERVICES.
DATE VERSION AUTHOR HISTORY 08/31/87 2.0 Allen Updates A number of changes have been made to version 1.0: 1) The name of the abstraction is no longer FILE_TYPE, but is LINK_TYPE instead. This just seemed to make more logical sense. The only change made to the source to reflect this was the text substitution LINK for FILE throughout. This includes the change from IN_FILE and OUT_FILE to IN_LINK and OUT_LINK for MODE_TYPE. In old programs where you used version 1.0, just make the same global text substitution to upgrade, and recompile. 2) The body has been changed to use the VAX's TASK_QIOW instead of STARLET.QIOW. This means that now the network i/o READ and WRITE operation will not suspend the entire VMS process while waiting for completion, only the individual Ada task. 3) The package no longer uses the VAX-specific 'MACHINE_SIZE attribute to determine the size of the message to be sent. Now 'SIZE is used on the object (as opposed to the type) to be sent.
