NDdeGetShareSecurity

The NDdeGetShareSecurity function is called to get the SECURITY_DESCRIPTOR associated with the DDE share. This is done usually for editing.

UINT NDdeGetShareSecurity(
  LPTSTR lpszServer,        // server to execute on
  LPTSTR lpszShareName,     // name of share to delete
  SECURITY_INFORMATION si,  // requested information
  PSECURITY_DESCRIPTOR pSD, // address of SD buffer
  DWORD cbSD,               // size of SD buffer
  LPDWORD lpcbsdRequired    // address of required size for SD buffer
);
 

Parameters

lpszServer

Address of the server name on which the DSDM resides.

lpszShareName

Address of the share name whose security descriptor is to be retrieved from the DSDM. This parameter must not be NULL.

si

Identifies the SECURITY_INFORMATION to be retrieved from the SECURITY_DESCRIPTOR associated with the share.

pSD

Address of a buffer that will accept the retrieved self-relative SECURITY_DESCRIPTOR. This parameter can be NULL. If this parameter is NULL, the DSDM determines the size of the requested security information and returns the number of bytes needed in the lpcbsdRequired parameter along with the NDDE_BUF_TOO_SMALL error code.

cbSD

Specifies the size of the buffer provided and referenced by the pSD parameter to accept the retrieved security descriptor. It must be 0 if pSD is NULL.

lpcbsdRequired

Address of the variable into which the actual size of the retrieved security descriptor is stored. This paramter 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 pSD parameter was NULL, it returns NDDE_BUF_TOO_SMALL.
