midiOutGetErrorTextW function (mmeapi.h)

  • Article

The midiOutGetErrorText function retrieves a textual description for an error identified by the specified error code.

Syntax

MMRESULT midiOutGetErrorTextW(
  MMRESULT mmrError,
  LPWSTR   pszText,
  UINT     cchText
);

Parameters

mmrError

Error code.

pszText

Pointer to a buffer to be filled with the textual error description.

cchText

Length, in characters, of the buffer pointed to by lpText.

Return value

Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following.

Return code Description
MMSYSERR_BADERRNUM
 The specified error number is out of range.
MMSYSERR_INVALPARAM
 The specified pointer or structure is invalid.

Remarks

If the textual error description is longer than the specified buffer, the description is truncated. The returned error string is always null-terminated. If cchText is zero, nothing is copied, and the function returns MMSYSERR_NOERROR. All error descriptions are less than MAXERRORLENGTH characters long.

Note

The mmeapi.h header defines midiOutGetErrorText as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
