NAME
       libnvme_get_telemetry_log - Get specified telemetry log

SYNOPSIS
       int libnvme_get_telemetry_log (struct libnvme_transport_handle *hdl ,
       bool create , bool ctrl , bool rae , size_t max_data_tx , enum
       nvme_telemetry_da da , struct nvme_telemetry_log **log , size_t *size
       );

ARGUMENTS
       hdl         Transport handle

       create      Generate new host initated telemetry capture

       ctrl        Get controller Initiated log

       rae         Retain asynchronous events

       max_data_tx Set the max data transfer size to be used retrieving
                   telemetry.

       da          Log page data area, valid values: enum nvme_telemetry_da.

       log         On success, set to the value of the allocated and retrieved
                   log.

       size        Ptr to the telemetry log size, so it can be returned

DESCRIPTION
       The total size allocated can be calculated as: (nvme_telemetry_log da
       size  + 1) * NVME_LOG_TELEM_BLOCK_SIZE.

RETURN
       0 on success, the nvme command status if a response was received (see
       enum nvme_status_field) or a negative error otherwise.
