It_PeekEvent
Use
Like the
It_GetEvent and the It_GetEventEX functions, It_PeekEvent gets the information of an event into the event structure.However, unlike It_GetEvent*, It_PeekEvent allows you to read the same event multiple times. (When using It_GetEvent, you can get a specific event only once. Any subsequent It_GetEvent call waits for the next event to occur. In contrast, using It_PeekEvent multiple times reads the same event).
You can use It_PeekEvent after sending an event (with It_SendEvent*) to look at the R/3 response. You can look at this response event multiple times before getting that event with an It_GetEvent* call.
Note, however, that if you first use It_GetEvent* to get the event, using It_PeekEvent cannot get that event anymore. It will be blocking for the next event to occur.
Syntax
