Re: how create many thread (over 256)

[long Smith]

compile:   gcc -o thread thread.c -lpthread   from this example，I know redhat7.3 - 8.0 can only create 256 thread(include main thread and the thread of create subthread)     #include <pthread.h> #include <errno.h> #include <strings.h> #include <unistd.h> #include <signal.h>   void *mysleep(int id) {         printf("threadid = %d pid = %d ppid = %d\n", id, getpid(), getppid());         sleep(20); }   void main(void) {         int l_i = 0;         pthread_t id[10000];           signal(SIGCLD, SIG_IGN);         printf("pid = %d\n",  getpid());           while(l_i < 2000) {                 int ret = 0;                 ret = pthread_create(&(id[l_i]), NULL, (void *)mysleep, l_i);                 if (ret != 0) {                         printf("errno = %d(%s) l_i = %d\n", errno, strerror(errno), l_i);                         exit(1);                 }                 l_i++;         }         sleep(100); }     ----- Original Message ----- From: 史绪良 To: [EMAIL PROTECTED] Sent: Wednesday, November 06, 2002 2:47 PM Subject: Re: how create many thread (over 256)   hello!!     can you help me??       my program need many thread, they will not exit never. but redhat linux7.3 - linux8.0 only create 256 thread!! how can I do??                                 thanks!!   can't use fork to create process,because all processes must share the memory！！       ----- Original Message ----- From: David Busby To: [EMAIL PROTECTED] Sent: Friday, January 10, 2003 12:32 PM Subject: Re: FAQ use fork() and create many processes, AFAIK you can have 1000s of processes   /B ----- Original Message ----- From: 史绪良 To: [EMAIL PROTECTED] Sent: Tuesday, November 05, 2002 18:18 Subject: FAQ   hello!!     can you help me??       my program need many thread, they will not exit never. but redhat linux7.3 - linux8.0 only create 256 thread!! how can I do??                                 thanks!!
