The lib folder contains the all important sockapi.lib file that you need to link your tasks
to.

THE SOCKET API LIBRARY
The socket API implemented for each of the node processors requires an initialization in each task before
use. The sock_init() call is provided for this purpose. This call accepts two of the (CHAN *) arguments
which were provided by the 3L loader to the main() for the task. The function below shows an extract
from the DSP task’s code.
int main(
int argc, char *argv[], char *envp[],
CHAN * in_ports[], int ins,
CHAN *out_ports[], int outs )
{
/*
** initialize socket API
This is a major component of the Ethernet support.
This routine
will create threads and allocate message buffers to support the
"sockapi.h" functions.
*/
sockapi_init = sock_init( in_ports[0], out_ports[0]);
if( sockapi_init != 0 )
{
printf(": sockapi init failure");
thread_stop();
}

An example of a 3L Diamond configuration file is shown below. This file shows the case of two
Sundance modules used as the embedded system. The root processor is a SMT395_VP30 and the node
is the SMT363.
