so confusing

#include<stdio.h>
#include<pthread.h>

void printMsg(void);

int main(){
pthread_t accnt1, accnt2;
pthread_create(accnt1, NULL, printMsg(), );
return 0;
}
void printMsg(){
printf("Hello PThread\n");
}

it shows:
tes.c: In function `main':
tes.c:8: error: syntax error before ')' token

is it the rite way to use pthread_create?

Don't know much about it but that comma doesn't look right

pthread_create(accnt1, NULL, printMsg(), );

That's how pthread_create call should look like:
int pthread_create(pthread_t * thread, pthread_attr_t * attr, void *(*start_routine)(void *), void * arg);

So, in your case, it should be:
pthread_create(accnt1, NULL, printMsg(),NULL );

BTW It's a good idea to check if pthread_create ends with a success.

you dont put the brackets printMsg(), it should be:
pthread_create(accnt1, NULL, printMsg, NULL); and optionally to make gcc stfu
pthread_create(accnt1, NULL, (void *)printMsg, NULL);

You're right infamous41md, I was copying.
