SccQueryInfo Function

  • Artikkeli

This function obtains status information for a set of selected files under source control.

Syntax

SCCRTN SccQueryInfo(
   LPVOID  pvContext,
   LONG    nFiles,
   LPCSTR* lpFileNames,
   LPLONG  lpStatus
);

Parameters

pvContext

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

nFiles

[in] Number of files specified in the lpFileNames array and the length of the lpStatus array.

lpFileNames

[in] An array of names of files to be queried.

lpStatus

[in, out] An array in which the source control plug-in returns the status flags for each file. For more information, see File Status Code.

Return Value

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

Value Description
SCC_OK Query was successful.
SCC_E_ACCESSFAILURE There was a problem with accessing the source control system, probably caused by network or contention issues. A retry is recommended.
SCC_E_PROJNOTOPEN The project is not open under source control.
SCC_E_NONSPECIFICERROR Nonspecific failure.

Remarks

If lpFileName is an empty string, there is currently no status information to update. Otherwise, it is the full path name of the file for which the status information may have changed.

The return array can be a bitmask of SCC_STATUS_xxxx bits. For more information, see File Status Code. A source control system may not support all bit types. For example, if SCC_STATUS_OUTOFDATE is not offered, the bit is just not set.

When using this function to check out files, note the following MSSCCI status requirements:

  • SCC_STATUS_OUTBYUSER is set when the current user has checked out the file.

  • SCC_STATUS_CHECKEDOUT cannot be set unless SCC_STATUS_OUTBYUSER is set.

  • SCC_STATUS_CHECKEDOUT is only set when the file is checked-out into the designated working directory.

  • If the file is checked-out by the current user into a directory other than the working directory, SCC_STATUS_OUTBYUSER is set but SCC_STATUS_CHECKEDOUT is not.
