SccHistory Function

  • Artikkeli

This function displays the history of the specified files.

Syntax

SCCRTN SccHistory(
   LPVOID    pvContext,
   HWND      hWnd,
   LONG      nFiles,
   LPCSTR*   lpFileNames,
   LONG      fOptions,
   LPCMDOPTS pvOptions
);

Parameters

pvContext

[in] The source control plug-in context structure.

hWnd

[in] A handle to the IDE window that the source control plug-in can use as a parent for any dialog boxes that it provides.

nFiles

[in] Number of files specified in the lpFileName array.

lpFileName

[in] Array of fully qualified names of files.

fOptions

[in] Command flags (currently not used).

pvOptions

[in] Source control plug-in-specific options.

Return Value

The source control plug-in implementation of this function is expected to return one of the following values:

Value Description
SCC_OK Version history was successfully obtained.
SCC_I_RELOADFILE The source control system actually modified the file on disk while fetching the history (for instance, by getting an old version of it), so the IDE should reload this file.
SCC_E_FILENOTCONTROLLED The file is not under source control.
SCC_E_OPNOTSUPPORTED The source control system does not support this operation.
SCC_E_NOTAUTHORIZED The user is not allowed to perform this operation.
SCC_E_ACCESSFAILURE There was a problem accessing the source control system, probably due to network or contention issues. A retry is recommended.
SCC_E_PROJNOTOPEN The project is has not been opened.
SCC_E_NONSPECIFICERROR Nonspecific failure. File history could not be obtained.

Remarks

The source control plug-in can display its own dialog box to show the history of each file, using hWnd as the parent window. Alternatively, the optional text output callback function supplied to the SccOpenProject can be used, if it is supported.

Note that under certain circumstances, the file being examined may change during the execution of this call. For example, the Visual SourceSafe history command gives the user a chance to get an old version of the file. In such a case, the source control plug-in returns SCC_I_RELOAD to warn the IDE that it needs to reload the file.

Note

If the source control plug-in does not support this function for an array of files, only the file history for the first file can be displayed.
