Subject: Re: how create many thread (over
256)
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);
}

use fork() and create many processes,
AFAIK you can have 1000s of processes
