IRAPISession::CeEnumDBVolumes (Windows Embedded CE 6.0)

1/6/2010

This method enumerates all mounted database volumes on a remote Windows Embedded CE–based device and returns the name for each.

Syntax

BOOL CeEnumDBVolumes (
  PCEGUID pceguid, 
  LPWSTR lpBuf,
  DWORD dwNumChars 
);

Parameters

• pceguid
  [in] To begin enumeration, set this parameter to the value returned by the CREATE_INVALIDGUID macro .

• lpBuf
  [out] Pointer to the allocated buffer that receives the database volume names.

• dwNumChars
  [in] Specifies the length, in characters, of the buffer.

Return Value

Nonzero indicates success. Zero indicates failure. To get extended error information, call IRAPISession::CeGetLastError and IRAPISession::CeRapiGetError. Possible values for CeGetLastError include the following:

• ERROR_INVALID_PARAMETER
  One of the parameters is invalid.

• ERROR_NO_MORE_ITEMS
  There are no more mounted volumes to enumerate.

• ERROR_INSUFFICIENT_BUFFER
  The specified buffer was not large enough.

Remarks

To begin enumeration, set the pceguid parameter to the value returned by the CREATE_INVALIDGUID macro.On successful completion, pceguid and lpBuf are set to the CEGUID and the database volume name of the first of the database volume, respectively. To continue enumeration, call IRAPISession::CeEnumDBVolumes and set the pceguid parameter to the value returned by the previous call. Continue until an error occurs.

If the return value is ERROR_INSUFFICIENT_BUFFER, reallocate the buffer and use the pceguid that was returned from the failure to resume the enumeration. This eliminates the need to completely restart the process.
