Since the regress tool 18 *limits 19 ** the output to a one line status:PASS or FAIL,all of the printf 20 *statements 21 ** have been handled with an if (debug_mode) statement. 22 ** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been 23 *updated to 24 ** recognize the return code from tha main program. 25 ***********************************************************************/ 26 27 /*********************************************************************** 28 ** Includes 29 ***********************************************************************/ 30 /* Used to get the command line option */ 31 #include "plgetopt.h" 32 33 #include "primpl.h" 34 #include "pprio.h" 35 #include "prnetdb.h" 36 37 #include <stdio.h> 38 #include <string.h> 39 #include <stdlib.h> 40 41 PRIntn failed_already = 0; 42 PRIntn debug_mode; 43 44 int main(int argc, char** argv) { 45 PRFileDesc *listenSock1, *listenSock2; 46 PRFileDesc* badFD; 47 PRUint16 listenPort1, listenPort2; 48 PRNetAddr addr; 49 PR_fd_set readFdSet; 50 char buf[128]; 51 PRInt32 retVal; 52 53 /* The command line argument: -d is used to determine if the test is being run 54 in debug mode.
