opcmsg C API
HPE Operations Agent provides a C-based 
API to generate messages for open message interface policies. The API can be used to generate messages from within a C program.
Note: The API can also be used to acknowledge previously generated messages, and to send monitor values to the HPE Operations Agent. Operations Connector does not support these uses.
For more information about the C-based message API, see the section "Agent Application Programming Interface" in the HPE Operations Agent Reference Guide PDF.
