CLUSCTL_RESOURCE_GET_NETWORK_NAME control code

项目
05/31/2018

Retrieves the name private property of a Network Name resource. This control code is unsupported by the other default resource types. Applications can use this control code as a parameter to the ClusterResourceControl function.

ClusterResourceControl( 
  hResource,                         // resource handle
  hHostNode,                         // optional host node
  CLUSCTL_RESOURCE_GET_NETWORK_NAME, // this control code
  NULL,                              // input buffer (not used)
  0,                                 // input buffer size (not used)
  lpOutBuffer,                       // output buffer: string
  cbOutBufferSize,                   // allocated buffer size (bytes)
  lpcbBytesReturned );               // actual size of resulting data (bytes)

Parameters

The following parameters are specific to this control code. For complete parameter descriptions, see ClusterResourceControl or ResourceControl.

lpOutBuffer: On a successful return, points to a null-terminated Unicode string containing the name of the resource.

Return value

ClusterResourceControl returns one of the following values:

ERROR_SUCCESS: The operation was successful. The lpcbBytesReturned parameter points to the actual size of the returned data.
ERROR_MORE_DATA: The output buffer pointed to by lpOutBuffer was not large enough to hold the data resulting from the operation. The lpcbBytesReturned parameter points to the size required for the output buffer.
System error code: The operation failed. The value of lpcbBytesReturned is unreliable.

Remarks

Do not use the CLUSCTL_RESOURCE_GET_NETWORK_NAME control code in any resource DLL entry point function. This control code can safely be called from a worker thread. For more information, see Function Calls to Avoid in Resource DLLs.

ClusAPI.h defines the 32 bits of CLUSCTL_RESOURCE_GET_NETWORK_NAME as follows (for more information, see Control Code Architecture).

Type bit	20	External (0x0)
Operation code	0 23	CLCTL_GET_NETWORK_NAME (0x169)
Access code	0 1	CLUS_ACCESS_READ (0x1)

Resource DLL Support

Do not support this control code in your resource DLL. Return ERROR_INVALID_FUNCTION.
