Anchor13544881354488 NetTCP_ConnCfgReTxMaxTimeout() is called by application function(s) and must not be called with the global network lock already acquired. It must block all other network protocol tasks by pending on and acquiring the global network lock (see “net“net.h Note #3”). This is required since an application's network protocol suite API function access is asynchronous to other network protocol tasks.
