The following flags are used for the TEXTOUTPROC function, which is a callback function that the IDE provides when it calls the SccOpenProject (see LPTEXTOUTPROC for details on the callback function).

If the IDE is asked to cancel the process, it may get one of the cancel messages. In this case, the source control plug-in uses SCC_MSG_STARTCANCEL to ask the IDE to display the Cancel button. After this, any set of normal messages may be sent. If any of these returns SCC_MSG_RTN_CANCEL, then the plug-in quits the operation and returns. The plug-in also polls SCC_MSG_DOCANCEL periodically to determine if the user has canceled the operation. When all operations are done, or if the user has canceled, the plug-in sends SCC_MSG_STOPCANCEL. The SCC_MSG_INFO, SCC_MSG_WARNING, and SCC_MSG_ERROR types are used for messages that get displayed in the scrolling list of messages. SCC_MSG_STATUS is a special type that indicates that the text should show up in a status bar or temporary display area. It does not remain permanently in the list.
