Function Documentation

int anjay_send_batch_add_double(anjay_send_batch_builder_t *builder, anjay_oid_t oid, anjay_iid_t iid, anjay_rid_t rid, anjay_riid_t riid, avs_time_real_t timestamp, double value)

Adds a value to batch builder.

IMPORTANT NOTE: If timestamp is earlier than 1978-07-04 21:24:16 UTC (2**28 seconds since Unix epoch), then it’s assumed to be relative to some arbitrary point in time, and will be encoded as relative to “now”. Otherwise, the time is assumed to be an Unix timestamp, and encoded as time since Unix epoch. See also: RFC 8428, “Requirements and Design Goals”

Parameters:

  • builder – Pointer to batch builder

  • oid – Object ID, MUST NOT be UINT16_MAX

  • iid – Instance ID, MUST NOT be UINT16_MAX

  • rid – Resource ID, MUST NOT be UINT16_MAX

  • riid – Resource Instance ID, UINT16_MAX for no RIID

  • timestamp – Time related to value being sent (e.g. when the measurement corresponding to the passed value was made)

  • value – Value to add to the batch.

Returns:

0 on success, negative value otherwise. In case of failure, the builder is left unchanged.
