pSOS+ System Calls sm_ident
Notes
See Also
1. Internally, the pSOS+ kernel treats a semaphore name as a 32-bit integer.
However, when the application calls the kernel through the pSOS+ C language
API, it passes the semaphore name as a four-byte character array.
2. The pSOS+ kernel does not check for duplicate semaphore names. If duplicate
semaphore names exist, an sm_ident() call can return the smid of any
semaphore with the duplicate name.
Multiprocessor Considerations
1. sm_ident() converts a semaphore's name to its smid by using a search order
determined by the node input parameter, as described in pSOSystem System
Concepts. Because semaphores 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, then the pSOS+m
kernel makes a sm_ident() RSC to the master node.
