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 #include "nspr.h" #define NUM_THREADS 1 #define BASE_PORT 8000 #define DEFAULT_ACCEPT_TIMEOUT 2 typedef struct threadInfo { PRInt16 id; PRInt16 accept_timeout; PRLock *dead_lock; PRCondVar *dead_cv; PRInt32 *alive; } threadInfo; PRIntn failed_already=0; PRIntn debug_mode; void thread_main(void *_info) { threadInfo *info = (threadInfo *)_info; PRNetAddr listenAddr; PRNetAddr clientAddr; PRFileDesc *listenSock = NULL; PRFileDesc *clientSock; PRStatus rv; if (debug_mode) printf("thread %d is alive\n", info->id); listenSock = PR_NewTCPSocket(); if (!listenSock) { if (debug_mode) printf("unable to create listen socket\n"); goto dead; } listenAddr.inet.family = AF_INET; listenAddr.inet.port = PR_htons(BASE_PORT + info->id); listenAddr.inet.ip = PR_htonl(INADDR_ANY); rv = PR_Bind(listenSock, &listenAddr); if (rv == PR_FAILURE) { if (debug_mode) printf("unable to bind\n"); goto dead; } rv = PR_Listen(listenSock, 4); if (rv == PR_FAILURE) { if (debug_mode) printf("unable to listen\n"); goto dead; } if (debug_mode) printf("thread %d going into accept for %d seconds\n", info->id, info->accept_timeout + info->id); clientSock = PR_Accept( listenSock, &clientAddr, PR_SecondsToInterval( info->accept_timeout + info->id)); if (clientSock == NULL) { if (PR_GetError() == PR_IO_TIMEOUT_ERROR) if (debug_mode) { printf("PR_Accept() timeout worked!\n"); printf("TEST FAILED!
