Use the -l c option to qcc to link against this library. This library is usually included automatically.
The resmgr_ocb() function queries the internal resource manager database, which maps client connections to the server Open Control Block (OCB), to retrieve the OCB pointer that was previously bound using resmgr_open_bind().
(QNX Neutrino 7.1 or later) The resmgr_ocb_iofuncs() function combines the functionality of resmgr_ocb() and resmgr_iofuncs() into a single operation.
A pointer to the OCB for the matching binding, or NULL if the binding can't be found or an error occurred.
The OCB can be a structure that you define. By default, it's of type iofunc_ocb_t.
