This function updates a list of files for a particular source control command and supplies source control status on all given files.
[in] The source control plug-in context structure.
[in] The source control command that will be applied to all files in the lpFileNames array (see Command Code Enumerator for a list of possible commands).
[in] Number of files in the lpFileNames array.
[in] An array of file names known to the IDE.
[in] The IDE callback function to call to add and remove files (see POPLISTFUNC for details).
[in] Value that is to be passed unchanged to the callback function.
[in, out] An array for the source control plug-in to return the status flags for each file.
[in] Command flags (see the "PopulateList flag" section of Bitflags Used by Specific Commands for details).
The source control plug-in implementation of this function is expected to return one of the following values:
This function examines the list of files for its current status. It uses the pfnPopulate callback function to notify the caller when a file does not match the criteria for the nCommand. For example, if the command is SCC_COMMAND_CHECKIN and a file in the list is not checked out, then the callback is used to inform the caller. Occasionally, the source control plug-in may find other files that could be part of the command and add them. This allows, for example, a Visual Basic user to check out a .bmp file that is used by his or her project but does not appear in the Visual Basic project file. A user chooses the Get command in the IDE. The IDE will display a list of all files that it thinks the user can get, but before the list is shown, the SccPopulateList function is called to make sure the list to be displayed is up to date.
The IDE builds a list of files that it thinks the user can get. Before it displays this list, it calls the SccPopulateList function, giving the source control plug-in the opportunity to add and delete files from the list. The plug-in modifies the list by calling the given callback function (see POPLISTFUNC for more details).
The plug-in continues to call the pfnPopulate function, which adds and deletes files, until it is finished and then returns from the SccPopulateList function. The IDE can then display its list. The lpStatus array represents all files in the original list passed in by the IDE. The plug-in fills in the status of all these files in addition to making use of the callback function.
A source control plug-in always has the option to simply return immediately from this function, leaving the list as it is. If a plug-in implements this function, it can indicate this by setting the SCC_CAP_POPULATELIST capability bitflag in the first call to the SccInitialize Function. By default, the plug-in should always assume that all items being passed in are files. However, if the IDE sets the SCC_PL_DIR flag in the fOptions parameter, all the items being passed in are to be considered directories. The plug-in should add all the files that belong in the directories. The IDE will never pass in a mixture of files and directories.
