- RecvRtt = Ping ( IPAddr )
- Sends an ICMP echo request to a remote host
Syntax: RecvRtt = Ping ( IPAddr )
| Part |
Type |
Description |
| RecvRtt |
Long |
Round Trip Time (in milliseconds) for the ping packet. If an error
occurs, RecvRtt will equal -1. Depending on the error, however, you may still be
able to get the Round Trip Time with the RecvRtt
property. |
| IPAddr |
Long |
IP address (in network byte order) of the remote host to which the ping
packet should be sent. You can obtain the numeric IP address from an address string with HexLookup. |
The Ping method sends an ICMP echo request packet to a remote host.
The remote host will typically respond with an echo reply, and the Ping
method returns with the total round trip time.
In practice, the remote host may not respond, or the echo packets may get lost in
transit. In this case, Ping times out after the period specified by Timeout and returns -1. Check the Error property for an error code.
