Bitflags Used by Specific Commands

The behavior of a number of functions in the Source Control Plug-in API can be modified by setting one or more bits in a single value. These values are known as bitflags. The various bitflags used by the Source Control Plug-in API are detailed here, grouped by the function that uses them.

Checked Out Flag

This flag can be set for either the SccAdd Function or SccCheckin Function.

Flag

Value

Description

SCC_KEEP_CHECKEDOUT

0x1000

Keep the file checked out.

Add Flags

These flags are used by the SccAdd Function.

Flag

Value

Description

SCC_FILETYPE_AUTO

0x00

The source control plug-in is expected to automatically detect whether the file is text or binary.

SCC_FILETYPE_TEXT

0x01

File type is text.

SCC_FILETYPE_BINARY

0x04

File type is binary.

NoteNote
SCC_FILETYPE_TEXT and SCC_FILETYPE_BINARY flags are mutually exclusive. Set exactly one or neither.

SCC_ADD_STORELATEST

0x02

Store latest version only (no deltas).

Diff Flags

The SccDiff Function uses these flags to define the scope of a diff operation. The SCC_DIFF_QD_xxx flags are mutually exclusive. If any one of them is specified, then no visual feedback is to be given. In a "quick diff" (QD), the plug-in does not determine how the file is different, only if it is different. If none of these flags is specified, a "visual diff" is done; detailed file differences are computed and displayed. If the requested QD is not supported, the plug-in moves to the next best one. For instance, if the IDE requests a checksum, and the plug-in does not support it, the plug-in does a full-contents check (still much faster than a visual display).

Flag

Value

Description

SCC_DIFF_IGNORECASE

0x0002

Ignore case differences.

SCC_DIFF_IGNORESPACE

0x0004

Ignore white-space differences.

NoteNote
The SCC_DIFF_IGNORECASE and SCC_DIFF_IGNORESPACE flags are optional bitflags.

SCC_DIFF_QD_CONTENTS

0x0010

QD by comparing entire file contents.

SCC_DIFF_QD_CHECKSUM

0x0020

QD by checksum.

SCC_DIFF_QD_TIME

0x0040

QD by file date/time stamp.

SCC_DIFF_QUICK_DIFF

0x0070

This is a mask used to check all the QD bitflags. It should not be passed into a function; the three QD bitflags are mutually exclusive. QD always means no display of UI.

PopulateList Flag

This flag is used by the SccPopulateList Function in the fOptions parameter.

Flag

Value

Description

SCC_PL_DIR

0x00000001L

The IDE is passing directories, not files.

PopulateDirList Flags

These flags are used by the SccPopulateDirList Function in the fOptions parameter.

Option Value

Value

Description

SCC_PDL_ONELEVEL

0x0000

Examine only one level of directories for directories (this is the default).

SCC_PDL_RECURSIVE

0x0001

Recursively examine all directories under each given directory.

SCC_PDL_INCLUDEFILES

0x0002

Include file names in the examination process.

OpenProject Flags

These flags are used by the SccOpenProject Function in the dwFlags parameter.

Option Value

Value

Description

SCC_OP_CREATEIFNEW

0x00000001L

If project doesn't exist in source control, create it. If this flag is not set, prompt user for project to create (unless SCC_OP_SILENTOPEN flag is specified).

SCC_OP_SILENTOPEN

0x00000002L

Do not prompt user to create a project; just return SCC_E_UNKNOWNPROJECT.

Get Flags

These flags are used by the SccGet Function and the SccCheckout Function.

Flag

Value

Description

SCC_GET_ALL

0x00000001L

The IDE is passing directories, not files: Get all files in these directories.

SCC_GET_RECURSIVE

0x00000002L

The IDE is passing directories: Get these directories and all their subdirectories.

nOption Values

These flags are used by the SccSetOption Function in the nOption parameter.

Flag

Value

Description

SCC_OPT_EVENTQUEUE

0x00000001L

Set status of the event queue.

SCC_OPT_USERDATA

0x00000002L

Specify user data for SCC_OPT_NAMECHANGEPFN.

SCC_OPT_HASCANCELMODE

0x00000003L

The IDE can handle cancel

SCC_OPT_NAMECHANGEPFN

0x00000004L

Set a callback for name changes.

SCC_OPT_SCCCHECKOUTONLY

0x00000005L

Disable source control plug-in UI checkout and do not set working directory.

SCC_OPT_SHARESUBPROJ

0x00000006L

Add from the source control system to specify a working directory. Try to share into the associated project if it is a direct descendant.

dwVal Bitflags

These flags are used by the SccSetOption Function in the dwVal parameter.

Flag

Value

Description

Used by nOption value

SCC_OPT_EQ_DISABLE

0x00L

Suspends event queue activity.

SCC_OPT_EVENTQUEUE

SCC_OPT_EQ_ENABLE

0x01L

Enables event queue logging.

SCC_OPT_EVENTQUEUE

SCC_OPT_HCM_NO

0L

(Default) Has no cancel mode; plug-in must supply if desired.

SCC_OPT_HASCANCELMODE

SCC_OPT_HCM_YES

1L

IDE handles cancel.

SCC_OPT_HASCANCELMODE

SCC_OPT_SCO_NO

0L

(Default) OK to check out from plug-in UI; working directory is set.

SCC_OPT_SCCCHECKOUTONLY

SCC_OPT_SCO_YES

1L

No plug-in UI checkout, no working directory.

SCC_OPT_SCCCHECKOUTONLY
