/* The following NetLabel payloads are supported by the CALIPSO subsystem.
|
|
*
|
|
* o ADD:
|
|
* Sent by an application to add a new DOI mapping table.

*
|
|
* Required attributes:
|
|
*
|
|
* NLBL_CALIPSO_A_DOI
|
|
* NLBL_CALIPSO_A_MTYPE
|
|
*
|
|
* If using CALIPSO_MAP_PASS no additional attributes are required.
|
|
*
|
|
* o LIST:
|
|
* Sent by an application to list the details of a DOI definition. On
|
|
* success the kernel should send a response using the following format.
|
|
*
|
|
* Required attributes:
|
|
*
|
|
* NLBL_CALIPSO_A_DOI
|
|
*
|
|
* The valid response message format depends on the type of the DOI mapping,
|
|
* the defined formats are shown below.

|
* Required attributes:
|
|
*
|
|
* NLBL_CALIPSO_A_MTYPE
|
|
*
|
|
* If using CALIPSO_MAP_PASS no additional attributes are required.
|
|
*
|
|
* o LISTALL:
|
|
* This message is sent by an application to list the valid DOIs on the
|
|
* system. When sent by an application there is no payload and the
|
|
* NLM_F_DUMP flag should be set. The kernel should respond with a series of
|
|
* the following messages.
