.SH DESCRIPTION
|
|
|
|
.PP
|
|
|
|
This function sets a \fIcallback\fP in the given ares channel handle. This
|
|
|
|
callback function will be invoked after the socket has been created, but
|
|
|
|
before it has been connected to the remote server, which is an ideal time
|
|
|
|
to configure various socket options. The callback must return ARES_SUCCESS
|
|
|
|
if things are fine, or return -1 to signal an error. A returned error will
|
|
|
|
abort the ares operation.
