xslm_query_server_info

SYNOPSIS

#include <libxslm.h>

xslm_uint32 xslm_query_server_info(
    xslm_uuid       server_id,
    xslm_uint32     * server_buffer_length,
    xslm_bin_string * server_buffer,
    xslm_uint32     * status,
    xslm_uint32     auth_token,
    xslm_bin_string * auth_signature,
    xslm_uuid       * auth_lic_sys_id
);

DESCRIPTION

xslm_query_server_info() returns the list of XSLM data element IDs supported by the specified server.

INPUT PARAMETERS

server_id

Identification of server to which this request is being directed.

auth_token

A 32-bit arbitrary value created by the application and used as part of the licensing system authentication process. See Process Description for more information.

INPUT/OUTPUT PARAMETERS

server_buffer_length

As an input parameter, the length of the buffer to receive the results of the call. A value of zero on input indicates a request for the size of the buffer required to contain the all the results of the call. No data is returned in the server buffer when a value of zero is passed.

As an output parameter the length of usable data returned in the server buffer or the size of the buffer required to contain the entire result if the input value is zero.

Note that the buffer must be large enough to contain the entire result of the call. If it is not large enough, no data is placed in the buffer and the output value of server_buffer_length contains the buffer length needed to contain the entire result.

OUTPUT PARAMETERS

server_buffer

Pointer to the buffer which contains a list of all the data element IDs supported by the specified server.

status

Completion status. Detailed error code directly addressable by the caller. This value is set to XSLM_STATUS_OK if no error occurred. For other messages, see ERRORS.

auth_signature

An area large enough to contain a 16-byte digital signature created by the licensing system from the input parameters and auth_token. Used as part of the licensing system authentication process.

auth_lic_sys_id

A unique identifier for the particular type of licensing system handling the current license instance. Used as part of the licensing system authentication process.

RETURN VALUE

XSLM_OK

Query completed successfully

XSLM_COMM_ERR

Communications problem

XSLM_CERT_ERR

Problems with the license and/or certificate

XSLM_RESRC_UNAVL

Resources unavailable

XSLM_PARM_ERR

Bad parameters passed

XLSM_AUTH_ERROR

Requester is not authorized

ERRORS

The function return value gives an overall indication of the success or failure of the call. In addition, the status parameter will be set to one of the following values, to further help point to the reason for a failed request.

Note:

In the future, additional values may be defined for the status variable. An application must not rely upon these being the only possible values.

Return Value	Status Value	Explanation
XSLM_OK	XSLM_STATUS_OK	No errors occurred
XSLM_COMM_ERR	XSLM_COMM_UNAVAIL	Communications problem
XSLM_RESRC_UNAVL	XSLM_NO_RES	Local platform specific environmental problems
	XSLM_SERVER_ERROR	Unrecoverable environmental error was encountered by the license server
XSLM_PARM_ERR	XSLM_BAD_PARM	One or more parameters were not correct
	XSLM_BAD_BUFFER_LENGTH	The non-zero value for the buffer length was too small for the certificate being retrieved.
	XSLM_BAD_SERVER_ID	The server_id specified does not correspond to a known server
XSLM_AUTH_ERROR	XSLM_NOT_AUTHORIZED	The requester is not authorized to perform the requested action

OUTPUT DATA

A data element, LICENSE_SERVER_INFORMATION (see Data Elements for details).
