# RtlAppendUnicodeStringToString(3w)

## NAME

**RtlAppendUnicodeStringToString** (NTDLL.@)

## SYNOPSIS

NTSTATUS RtlAppendUnicodeStringToString\
  (\
   UNICODE\_STRING\*       *dest*,\
   const UNICODE\_STRING\* *src*\
  )

## PARAMS

*dest* **\[In/Out\]**  Buffered unicode string to which *src* is concatenated.

*src* **\[In\]**  Buffered unicode string to be concatenated.

## DESCRIPTION

Concatenates two buffered unicode strings.

## RETURNS

**Success:** **STATUS\_SUCCESS**. *src* is appended to *dest*.

**Failure:** **STATUS\_BUFFER\_TOO\_SMALL**, if the buffer of *dest* is too small to hold the concatenated string.

## NOTES

if *src-\>length* is zero *dest* is unchanged. *dest* is **' '** terminated when the MaximumLength allows it. When *dest* fits exactly in MaximumLength characters the **' '** is omitted.

## DIFFERENCES

Does not write in the *src-\>Buffer* beyond MaximumLength when MaximumLength is odd as the native function does.

## IMPLEMENTATION

Declared in **"winternl.h"**.

Implemented in **"dlls/ntdll/rtlstr.c"**.

Debug channel **"ntdll"**.
