Comments
Caller to PING_OPEN API must initialize structure members:
remoteHostNamePtr... who to "ping"
pingInterval... block repetition rate in seconds
pingDataLength... size of ping data blocks
count... set to zero, if ping should run forever
The remainder of the data structure is managed within the API functions.
