Error
A capture
window uses error notification messages to notify your application of AVICap
errors, such as running out of disk space, attempting to write to a read-only
file, failing to access hardware, or dropping too many frames. The content of
an error notification includes a message identifier and a formatted text string
ready for display. Your application can use the message identifier to filter
the notifications and limit the messages to present to the user. A message
identifier of zero indicates a new operation is starting and the callback
function should clear any displayed error message.
