Cancel the pattern matching of a text.
void strpattern_cancel(long id, int *err)
The ID of the text whose pattern matching is to be canceled.
STRPATTERN_EOK if there is no error. STRPATTERN_ENOTFOUND if no text with the given ID is scheduled for pattern matching.
This function cancels the pattern matching of a doucment or text with the specified ID. The ID is matched against the IDs assigned when texts are scheduled for pattern matching.
A scheduled pattern matching is canceled only if the pattern matching is not completed when this function executes.
Successfully cancelling a scheduled pattern matching means that the callback provided at the time of scheduling is not invoked for this instance of pattern matching.
