Module Name:
|

|
|
|
||
|
|
CheckTAPIVersionParameters.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Hooks the call to lineNegotiateAPIVersion so that device 0 doesn't fail
|
||
|
|
causing the application to stop querying devices.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim. Could potentially be general, but requires
|
||
|
|
research.
