int phImageCapture::close  )  [virtual]
 

On close, the class should retain as much of the current state as possible after this call to open. That way, when the class is reopened with path = NULL, the class can use all the previous information. Also, if any of the picture settings were changed (in phImageCapture), they will remain consistent with the last values and won't have to be set again.

If this fails it should return phFail to signal the called something bad happened. If the object isn't in an opened state, then this should be nice and return a value greater than or equal to 0.

on close, the class retains all previous knowledge except the device capabilities.

Reimplemented from phCaptureInterface.

Reimplemented in phAvcodecSource, phNetSource, V4LCapture, VFWSource, and phNetSource.
