EngUnicodeToMultiByteN function (winddi.h)

The EngUnicodeToMultiByteN function converts the specified Unicode string into an ANSI string using the current ANSI code page.

Syntax

ENGAPI VOID EngUnicodeToMultiByteN(
  [out]           PCHAR  MultiByteString,
  [in]            ULONG  MaxBytesInMultiByteString,
  [out, optional] PULONG BytesInMultiByteString,
  [in]            PWSTR  UnicodeString,
  [in]            ULONG  BytesInUnicodeString
);

Parameters

[out] MultiByteString

Pointer to the buffer that receives the resultant ANSI string.

[in] MaxBytesInMultiByteString

Specifies the maximum number of bytes to be written to MultiByteString. If this value is too small, causing MultiByteString to be a truncated equivalent of UnicodeString, then no error condition results.

[out, optional] BytesInMultiByteString

Pointer to a ULONG that receives the number of bytes written to MultiByteString.

[in] UnicodeString

Pointer to the Unicode source string that is to be converted to ANSI.

[in] BytesInUnicodeString

Specifies the number of bytes in UnicodeString.

Return value

None
