NAME

VarBstrCmp (OLEAUT32.314)

SYNOPSIS

HRESULT VarBstrCmp
 (
  BSTR  pbstrLeft,
  BSTR  pbstrRight,
  LCID  lcid,
  DWORD dwFlags
 )

DESCRIPTION

Compare two BSTR values.

PARAMS

pbstrLeft [In] Source.

pbstrRight [In] Value to compare.

lcid [In] LCID for the comparison.

dwFlags [In] Flags to pass directly to CompareStringW(3w).

RETURNS

VARCMP_LT, VARCMP_EQ or VARCMP_GT indicating that pbstrLeft is less than, equal to or greater than pbstrRight respectively.

NOTES

VARCMP_NULL is NOT returned if either string is NULL unlike MSDN states. A NULL BSTR pointer is equivalent to an empty string. If LCID is equal to 0, a byte by byte comparison is performed.
