pips-clientDescription:
This data type provides the prototype for functions that handle new data events for a given publication. These functions can be attached to a publication, and allow the caller to be notified about which publication received new data and about which endpoint generated the data sample.
Returns:
The PiPS event framework expects the handler to return a negative value and set errno if it encounters an error, and return a value greater than or equal to zero to indicate success.
