pthread_create Function
I trying to create multi thread programming in C.

I am getting ENOSYS error from pthread_create function. I would appreciate if someone can assit me. I am calling function thread_loop twice. But it is executing only once. Gettint error from pthread_create function. Thanks.


#include <pthread.h>
#include <errno.h>


void* thread_loop(void* data)
{

int i = 0;
long j = 0;

printf("Inside the function \n");

for (i = 0 ; i<5; i++)
{
for (j=0; j<900 ; j++);
printf("I value %d \n", i);
}

}

void main(int argc, char *argv[] )
{


int i = 1;

pthread_t thread1 ;

int ret ;


ret = pthread_create(&thread1, NULL, thread_loop, (void*) &i) ;


switch (ret)
{

case 0 : printf("pthread_create function Success \n"); break ;

case EAGAIN : printf("Error : No more processes \n"); break ;

case ENOSYS : printf("Error : Function not implemented \n"); break ;

case EINVAL : printf("Error : Invalid Argument \n"); break ;

case EPERM : printf("Error : Not super-user \n"); break ;

default : printf("Other error from pthread_create \n"); break ;

}

printf("End Of Main %d \n ", ret);

thread_loop(&i);

}
