This procedure is repeatedly called to find all adapters. It searches the list of all adapters, calling
|
||
|
|
their find routine until an adapter is located. It is passed a pointer to an int (Context), which is zero on
|
||
|
|
the first call. The find routine updates the Context to a value it can use to restart the search. Only one
|
||
|
|
adapter is found per call. Subsequent adapters are found on later calls. An adapters find routine will be
|
||
|
|
called repeatedly, until it returns a zero, which means it found no additional adapters. When an adapter is
|
||
|
|
found, the passed adapter structure (HA) is filled in, and a value of 1 is returned.
