DCN Next Generation Open Interface Release 2.0 Simultaneous Interpretation
en | 132
APPENDIX C. EXAMPLES
In the example below the remote functions and update notifications, that are defined in this
document as constant values for the wFnId parameter of the message (see [SRS_INF]), are
presented as functions described in a ‘C’ syntax. The parameter structures of these functions
are according the input, output or notify structures described in the appropriate section.
For every function it is assumed that the function will create its structure, transport the
parameters to the CCU and wait for the result information coming from the CCU.
For both the remote functions and the update notifications the same names are used as their
identifier, but without the constant mark “C” and using mixed case names. So, e.g. remote
function IN_C_START_IN_APP shall as function be referenced as:
IN_Start_IN_App (void);
Appendix C.1 Simultaneous Interpretation Control
This example shows the minimum steps to be taken for controlling the IN application
First we have to start controlling the IN application on the CCU.
