Reserved2 );
BoardId : board ID returned by el_OpenHW
Frequency : Frequency in Hz
Reserved1 :
DESCRIPTION: Sets the pixel clock generated on the board. The value has to be specified in Hz. If a
camera uses its own clock, the value has to be set to the frequency of the camera clock, because it is
used for timing calculations. The realized and the desired frequency can be obtained with
el_GetPixelClock.
RETURN VALUE:
0 if OK
-1 if ERROR. See el_GetErrorCode for details.

el_TestAcq ( long BoardId );
DESCRIPTION: Test if acquisition is active (on). This function can be used as a replacement for
el_WaitAcqEnd if the programmer wants to check different other conditions or works on the image while
he is waiting for the end of a acquisition e.g. useful in a multitasking environment.
RETURN VALUE:
1 if aquisition is running
0 if aquisition is not running
-1 if ERROR. See el_GetErrorCode for details.
Single buffer acquisition
A single snap was triggered with acquisition mode EL_SNAP. Then el_TestAcq() returns '0' after the
frame was transferred into memory. During acquisition '1' is returned.
Image sequence acquisition:
A single sequence acquisition was triggered with acquisition mode EL_SNAP. Then el_TestAcq() returns
'0' after the last frame of the sequence was transferred to memory. During sequence acquisition '1' is
returned.
CAVEATS: This function looks at the DMA transfer of data into data memory and not directly to the
camera's frame timing.
