GetSystemVersionString

The GetSystemVersionString and GetSystemVersionStringWide methods return a string that describes the target's operating system version.

HRESULT
  IDebugControl4::GetSystemVersionString(
    IN ULONG  Which,
    OUT OPTIONAL PSTR  Buffer,
    IN ULONG  BufferSize,
    OUT OPTIONAL PULONG  StringSize
    );

HRESULT
  IDebugControl4::GetSystemVersionStringWide(
    IN ULONG  Which,
    OUT OPTIONAL PWSTR  Buffer,
    IN ULONG  BufferSize,
    OUT OPTIONAL PULONG  StringSize
    );

Parameters

Which

Specifies which version string to return. The possible values are listed in the following table.

Value	Version string
DEBUG_SYSVERSTR_SERVICE_PACK	Returns a description of the service pack for the target's operating system. For example, "Service Pack 1".
DEBUG_SYSVERSTR_BUILD	Returns a description of the target's operating system build version. For example, "kernel32.dll version: 5.1.2600.1106 (xpsp1.020828-1920)".

Buffer

Receives the version string. If Buffer is NULL, this information is not returned.

BufferSize

Specifies the size, in characters, of the buffer that Buffer specifies.

StringSize

Receives the size, in characters, of the string that identifies the build. If SizeString is NULL, this information is not returned.

Return Value

S_OK: The method was successful.
S_FALSE: The method was successful. However, the buffer was too small, so the string was truncated.

This method may also return error values. See Return Values for more details.

Interface Version

GetSystemVersionString and GetSystemVersionStringWide are available in IDebugControl4 and later versions.
