Since the regress tool limits ** the output to a one line status:PASS or FAIL,all of the printf statements ** have been handled with an if (debug_mode) statement. ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to ** recognize the return code from tha main program. ***********************************************************************/ /*********************************************************************** ** Includes ***********************************************************************/ /* Used to get the command line option */ #include "plgetopt.h" #include "prinit.h" #include "prio.h" #include "prlog.h" #include "prprf.h" #include "prerror.h" #include "prnetdb.h" #include "obsolete/probslet.h" #include <stdio.h> #include <string.h> #include <stdlib.h> PRIntn failed_already=0; PRIntn debug_mode; static void clientThreadFunc(void *arg) { PRUintn port = (PRUintn) arg; PRFileDesc *sock; PRNetAddr addr; char buf[128]; int i; addr.inet.family = PR_AF_INET; addr.inet.port = PR_htons((PRUint16)port); addr.inet.ip = PR_htonl(PR_INADDR_LOOPBACK); PR_snprintf(buf, sizeof(buf), "%hu", addr.inet.port); for (i = 0; i < 5; i++) { sock = PR_NewTCPSocket(); PR_Connect(sock, &addr, PR_INTERVAL_NO_TIMEOUT); PR_Write(sock, buf, sizeof(buf)); PR_Close(sock); } } int main(int argc, char **argv) { PRFileDesc *listenSock1, *listenSock2; PRFileDesc *fds0[10], *fds1[10], **fds, **other_fds; PRIntn nfds; PRUint16 listenPort1, listenPort2; PRNetAddr addr; PR_fd_set readFdSet; char buf[128]; PRThread *clientThread; PRInt32 retVal; PRIntn i, j; /* The command line argument: -d is used to determine if the test is being run in debug mode.
