// ParseMultiSz splits a UTF-16 encoded MULTI_SZ buffer (Windows style) into

// individual UTF-16 string slices.
|
|
//
|
|
// A MULTI_SZ buffer is a sequence of UTF-16 strings separated by single null
|
|
// terminators (0x0000) and terminated by an extra null (i.e., two consecutive
|
|
// nulls) to mark the end of the list.
|
|
//
|
|
// Example layout in memory (UTF-16):
|
|
//
|
|
// "foo\0bar\0baz\0\0"
|
|
//
|
|
// Given such a []uint16, this function returns a [][]uint16 where each inner
|
|
// slice is one null-terminated string segment without the trailing null.
|
|
//
|
|
// The returned slices reference the original buffer (no copying).
