Detailed Description

NDS1/2 client status structure.

The daq_t structure contains all the status and control information for the NDS client. It is used by each of the daq_access functions.

NDS server type.

NDS server type (NDS1=1 or NDS2=2)

int daq_t::sockfd

DAQD server socket.

Socket to which the connection request is made. By default this is 8088.

struct sockaddr_in daq_t::srvr_addr [read]

DAQD (NDS1) server IP address

Number of channels requested.

Number of channels request structures allocated.

Channel request list.

int daq_t::blocks

Block count??? zero for on-line transmission; positive for off-line

transmission block; dynamically allocated and reallocated as needed; freed in daq_recv_shutdown()

size of the above malloced data

struct signal_conv1* daq_t::s [read]

signal conversion data; dynamically allocated and reallocated as needed; freed in daq_recv_shutdown()

int daq_t::s_size

size of the above malloced data in elements (sizeof(signal_conv_t1) each)

int daq_t::rev

server protocol revision received by 'revision' command
