pSOS+ System Calls q_vident
Notes
See Also
1. Internally, the pSOS+ kernel treats a queue name as a 32-bit integer. However,
when the application calls the kernel through the pSOS+ C language API, it
passes the queue name as a four-byte character array.
2. The pSOS+ kernel does not check for duplicate queue names. If duplicate
names exist, a q_vident() call can return the qid of any queue with the
duplicate name.
Multiprocessor Considerations
1. q_vident() converts a queue's name to its qid using a search order
determined by the node input parameter as described in pSOSystem System
Concepts. Because queues created and exported by different nodes may not
have unique names, the result of this binding may depend on the order in which
the object tables are searched.
2. If the master node's Global Object Table must be searched, the local kernel
makes an q_vident() RSC to the master node.
