Using is_CameraStatus(), you can query and partly set various status information and settings.

Input Parameters

hCam

Camera handle

nInfo


IS_FIFO_OVR_CNT

Number of FIFO overruns. Is increased if image data gets lost because the USB bus is congested.

IS_SEQUENCE_CNT

Returns the sequence count. For is_CaptureVideo(), this parameter is set to 0. Each time the sequence buffer (image counter) changes, the counter is increased by 1.

IS_SEQUENCE_SIZE

Returns the number of sequence buffers.

IS_EXT_TRIGGER_EVENT_CNT

Returns the camera's internal count of external trigger events.

IS_TRIGGER_MISSED

Returns the number of unprocessed trigger signals. Is reset to 0 after each call.

IS_LAST_CAPTURE_ERROR

Returns the last image capture error, e.g. after a 'transfer failed' event. For a list of all possible error events, see is_GetCaptureErrorInfo().

IS_PARAMETER_SET_1

Indicates whether parameter set 1 including camera settings is present on the camera (read-only). See also is_SaveParameters().

Return values:

TRUE        Parameter set 1 present

FALSE        Parameter set 1 not present

ulValue


IS_GET_STATUS

Returns the information specified by nInfo.

Return Values

IS_SUCCESS

Function executed successfully

IS_NO_SUCCESS

General error message

Returns the information specified by nInfo.

Only if ulValue = IS_GET_STATUS

When used with
IS_LAST_CAPTURE_ERROR
