NDdeShareEnum

The NDdeShareEnum function is called to list the available DDE shares in the DSDM.

UINT NDdeShareEnum(
  LPTSTR lpszServer,           // server to execute on
  UINT nLevel,                 // must be 0
  LPBYTE lpBuffer,             // pointer to buffer
  DWORD cBufSize,              // size of buffer
  LPDWORD lpnEntriesRead,      // number of names returned
  LPDWORD lpcbTotalAvailable   // number of bytes available
);
 

Parameters

lpszServer

Address of the server name on which the DSDM resides.

nLevel

Must be 0.

lpBuffer

Address of a buffer supplied to accept the list of DDE shares. The list of DDE shares is stored as a sequence of null-separated strings terminating with a double null at the end. This parameter can be NULL. If lpBuffer is NULL, the DSDM returns the size of buffer required to hold the list of shares in the lpcbTotalAvailable field.

cBufSize

Specifies the size of the supplied buffer addressed by lpBuffer. Must be 0 if lpBuffer is NULL.

lpnEntriesRead

Address of a variable to receive the total number of shares being enumerated. Must not be NULL.

lpcbTotalAvailable

Address of a variable to receive the total number of bytes needed in the buffer to store the list of DDE shares. Must not be NULL.

Return Values

If the function succeeds, the return value is NDDE_NO_ERROR.

If the function fails, the return value is an error code, which can be translated into a text error message by calling NDdeGetErrorString. If the lpBuffer parameter is NULL, it returns NDDE_BUF_TOO_SMALL.
