This is the data structure that contains an individual signaling process’s configuration, with the following fields:
- installed
- Whether the signaling process is installed in the system.
- call_data
- Whether the signaling process supplies call information.
- SigprocClass
- The signaling process class: exchange data link, or common channel.
- SigprocCapabilitySet
- The capabilities of the signaling process.
This is the structure that the signaling process provides when opening the signaling interface using the sl_open() subroutine. The configuration information for a signaling process can be retrieved using the sl_query_config() subroutine.
Figure 1 shows how the SL_CONFIG_ST data structure is arranged.
