C++ (Cpp) np_trans_send Examples

Example #1

File: conn.c Project: EuroCorp/diod

void
np_conn_respond(Npreq *req)
{
    int n;
    Npconn *conn = req->conn;
    Npsrv *srv = conn->srv;

    xpthread_mutex_lock(&conn->wlock);
    n = np_trans_send(conn->trans, rc);
    xpthread_mutex_unlock(&conn->wlock);
    if (n < 0)
