L_LTANN_API L_INT L_AnnClipboardReady(pfReady)

L_BOOL * pfReady;

address of the variable to be updated

Determines whether the Windows clipboard contains an annotation object that can be pasted using the L_AnnCopyFromClipboard function.

Parameter Description
pfReady Address of the variable to be updated with a value indicating whether the clipboard contains an annotation object. Possible values are:
  Value Meaning
  TRUE The clipboard contains an annotation that can be copied.
  FALSE The clipboard does not contain an annotation that can be copied.



The function was successful.

< 1

An error occurred. Refer to Return Codes.


(Document and Medical) Before calling this function, you must declare a variable of data type L_BOOL. Then, pass the address of the variable in the pfReady parameter. This function will update the variable with the result of the test.

You can use L_AnnCopyToClipboard or L_AnnCutToClipboard to put valid annotation data on the clipboard. L_AnnCopyFromClipboard can be used to copy valid annotation data from the clipboard to a container.

For more information about loading and pasting automated annotations, refer to Loading and Pasting Automated Annotations.
