//
// DESCRIPTION: Get a property tag name string ("PR_*") given a property tag
// value.
//
// INPUT:
//
// [ulPropTag] -- Property tag value.
//
// OUTPUT:
//
// [lppszPropName] -- Ptr to ptr which will be set to returned property tag
// name string on success.
//
// RETURNS: NOERROR on success; E_INVALIDARG if bad input,
// E_NOT_ENOUGH_MEMORY if memory problems.
// Note that if the value is not found in the property tag
// string table, then a string of the following form is returned:
// - For PT_STRING8, "[S " <HexNumber> "]"
// - For PT_LONG, "[N " <HexNumber> "]"
// - For all others, "[" <HexNumber> "]"
//
// Notes: When it is no longer needed, the user should free
// *lppszPropName using MAPIFREEBUFFER().
// To avoid setting up a second table, this function was
// implemented using linear search, so performance is not
// great in the current implementation.
