Detailed Documentation
CSAP instance support resources and attributes.
Fields
unsigned int id
CSAP ID
unsigned int ref
CSAP reference count (have to be >0)
char* csap_type
Pointer to original CSAP type, proto[] entries are blocks of this string
asn_value* nds
ASN.1 value with CSAP specification
unsigned int depth
Number of layers in stack
csap_layer_t* layers
Array of protocol layer descroptors
unsigned int rw_layer
Index of layer in protocol stack responsible for read and write operations, usually lower
void* rw_data
Private data of read/write layer
unsigned int stop_latency_timeout
Maximum timeout for read operations in microseconds (it affects latency of stop/destroy operations)
unsigned int recv_timeout
Default receive timeout
struct timeval wait_for
Zero or moment of timeout current CSAP operation
struct timeval first_pkt
Moment of first good packet processed: matched or sent
struct timeval last_pkt
Moment of last good packet processed: matched or sent
pthread_cond_t event
Event condition
unsigned int state
Current state bitmask
pthread_mutex_t lock
Mutex for lock CSAP data which are changed from different threads (event, state, queue of received packets)
tad_send_context sender
Sender context
tad_recv_context receiver
Receiver context
unsigned int poll_id
ID of the last poll request
Methods
TAILQ_HEAD(tad_recv_op_context)
Receiver operations queue
LIST_HEAD(tad_poll_context)
List of poll requests
