Session In specifies the name of the camera you wish to reset. The default value is cam0.

error in describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

ci32.gif

code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.

cstr.gif

source identifies where an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.

Session Out is a unique reference to the camera. Session Out is the same as Session In.

Video Modes is an array of video modes supported by the current camera.

iu32.gif

Video Mode is the index for this video mode.

istr.gif

Video Mode Name VideoMode Name is the name of the video mode, such as 640 x 480 Mono8.

iu32.gif

Current Mode is the index into the Video Modes array of the current mode used by the camera.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI produces. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

istr.gif

source identifies where and why an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.
