The native thread will +** repeatedly call PR_AttachThread and PR_DetachThread. The +** primordial thread waits for this new thread to finish. +** +** Modification History: +** 13-May-97 AGarcia- Converted the test to accomodate the debug_mode flag. +** The debug mode will print all of the printfs associated with this test. +** The regress mode will be the default mode. 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. +** 12-June-97 Revert to return code 0 and 1. +***********************************************************************/ + +/*********************************************************************** +** Includes +***********************************************************************/ + +/* Used to get the command line option */ +#include "nspr.h" +#include "pprthred.h" +#include "plgetopt.h" + +#include <stdio.h> + +#ifdef WIN32 +#include <windows.h> +#include <process.h> +#elif defined(_PR_PTHREADS) +#include <pthread.h> +#include "md/_pth.h" +#elif defined(SOLARIS) +#include <thread.h> +#elif defined(OS2) +#define INCL_DOS +#define INCL_ERRORS +#include <os2.h> +#include <process.h> +#endif + +#define DEFAULT_COUNT 1000 +PRIntn failed_already=0; +PRIntn debug_mode; + + +int count; + + +static void +AttachDetach(void) +{ + PRThread *me; + PRInt32 index; + + for (index=0; index<count; index++) { + me = PR_AttachThread(PR_USER_THREAD, + PR_PRIORITY_NORMAL, + NULL); + + if (!me) { + fprintf(stderr, "Error attaching thread %d: PR_AttachThread failed\n", + count); + failed_already = 1; + return; + } + PR_DetachThread(); + } +} + +/************************************************************************/ + +static void Measure(void (*func)(void), const char *msg) +{ + PRIntervalTime start, stop; + double d; + + start = PR_IntervalNow(); + (*func)(); + stop = PR_IntervalNow(); + + d = (double)PR_IntervalToMicroseconds(stop - start); + if (debug_mode) { + printf("%40s: %6.2f usec\n", msg, d / count); + } +} + +#ifdef WIN32 +static unsigned __stdcall threadStartFunc(void *arg) +#else +static void * threadStartFunc(void *arg) +#endif +{ + Measure(AttachDetach, "Attach/Detach"); + + return 0; +} + +int main(int argc, char **argv) +{ +#ifdef _PR_PTHREADS + int rv; + pthread_t threadID; + pthread_attr_t attr; +#elif defined(SOLARIS) + int rv; + thread_t threadID; +#elif defined(WIN32) + DWORD rv; + unsigned threadID; + HANDLE hThread; +#elif defined(OS2) + int rv; + TID threadID; +#endif + + /* The command line argument: -d is used to determine if the test is being run + in debug mode.
