What system you've got?

Try to add
fflush(stdout);

After each call of printf()

This code was just an example. I just wanted to know, why bigger stack can allow to create more threads than default

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

#define MODIFY_STACK

void *fnc(void *a)
{
sleep(99999);
return NULL;
}

int main()
{
int i = 0;
pthread_t abc;...

Can someone explain me, why when I create new threads with stack bigger than default (using pthread_attr_setstacksize()) i can create more? Each thread has it's own stack, so how bigger stack can...

So I don't have to use -pthread or -D_REENTRANT?
I use -lpthread only when linking. For example:
gcc test.c -c -o test.o
gcc test.o -lpthread
Isn't that incorrect? (I know -l is linker option,...

Linux x86, x86_64 and FreeBSD x86, x86_64

I read somewhere that I should use -pthread instead of -lpthread as compiler/linker flag, or define _REENTRANT. Is this incorrect to use only -lpthread? (I use gcc)

Yes, I use linux.
Thanks for help

I saw this list, but I was confused, when I read sources of scandir() (from glibc):

[...]
#define READDIR __readdir
[...]
while ((d = READDIR (dp)) != NULL)
[...]


readdir() isn't thread...

I couldn't find anywhere informations about it. Is scandir() thread-safe?
