Macro Definition Documentation

◆ DEFAULT_MQTT_CONN_TIMEOUT_SEC

#define DEFAULT_MQTT_CONN_TIMEOUT_SEC 5

Definition at line 40 of file mqttcommon.h.

◆ GST_MQTT_ELEM_NAME_SINK

#define GST_MQTT_ELEM_NAME_SINK "mqttsink"

Definition at line 26 of file mqttcommon.h.

◆ GST_MQTT_ELEM_NAME_SRC

#define GST_MQTT_ELEM_NAME_SRC "mqttsrc"

Definition at line 27 of file mqttcommon.h.

◆ GST_MQTT_LEN_MSG_HDR

#define GST_MQTT_LEN_MSG_HDR 1024

Definition at line 29 of file mqttcommon.h.

◆ GST_MQTT_MAX_LEN_GST_CAPS_STR

#define GST_MQTT_MAX_LEN_GST_CAPS_STR 512

Definition at line 30 of file mqttcommon.h.

◆ GST_MQTT_MAX_NUM_MEMS

#define GST_MQTT_MAX_NUM_MEMS 16

GST_BUFFER_MEM_MAX in gstreamer/gstbuffer.c is 16. To represent each size of the memory block that the GstBuffer contains, GST_MQTT_MAX_NUM_MEMS should be 16.

Definition at line 36 of file mqttcommon.h.

◆ GST_MQTT_PACKAGE

#define GST_MQTT_PACKAGE "GStreamer MQTT Plugins"

Definition at line 23 of file mqttcommon.h.

◆ GST_US_TO_NS_MULTIPLIER

#define GST_US_TO_NS_MULTIPLIER 1000

Definition at line 38 of file mqttcommon.h.

◆ UNUSED

#define UNUSED ( expr ) do { (void)(expr); } while (0)

Definition at line 19 of file mqttcommon.h.

Typedef Documentation

◆ GstMQTTMessageHdr

typedef struct _GstMQTTMessageHdr GstMQTTMessageHdr

Defined a custom data type, GstMQTTMessageHdr.

GstMQTTMessageHdr contains the information needed to parse the message data at the subscriber side and is prepended to the original message data at the publisher side.

◆ mqtt_get_unix_epoch

typedef int64_t(* mqtt_get_unix_epoch) (uint32_t, char **, uint16_t *)

Definition at line 65 of file mqttcommon.h.

Function Documentation

◆ default_mqtt_get_unix_epoch()

static int64_t default_mqtt_get_unix_epoch	(	uint32_t	hnum,
		char **	hnames,
		uint16_t *	hports
	)

inlinestatic

A wrapper function of g_get_real_time () to assign it to the function pointer, mqtt_get_unix_epoch.

Definition at line 71 of file mqttcommon.h.
