Command Protocol Reference Guide
A - 17
<pctype>
The <pctype> argument defines the physical channel type of the physical
channels in the virtual channel. The <pctype> argument is a system defined
text argument that must be one of the pctypes listed in the vcdef section.
<num>
One or more <num> arguments are returned with the indices of the physical
channel(s) defined as part of the virtual channel.
vcundef Action
The vcundef action is a virtual channel definition command that undefines a
virtual channel that was previously defined with the vcdef action. Commands
with the vcundef action have the following syntax.
vcundef <label> <term>
Each of the command arguments is defined below.
<label>
The <label> argument is a user-defined text argument that defines the name of
the virtual channel to be undefined. If no virtual channel exists with the given
label, then SoundStructure will respond with an error message.
vcundef Acknowledgements
When a virtual channel definition command with the vcundef action is
successfully executed, SoundStructure will send an acknowledgement in the
same format as the command. The acknowledgement will be sent to all
interfaces.
As an example, consider a SoundStructure system that has a virtual channel
defined with “Stereo Mics” as its label. If the following command is sent to the
SoundStructure system,
vcundef "Stereo Mics"
then the following acknowledgement will be generated and sent to all
interfaces.
vcundef "Stereo Mics"
vcrename Action
The vcrename action is a virtual channel definition command that changes
then name of a virtual channel. Commands with the vcrename action have the
following syntax.
vcrename <label> <new-label>
