> Taking into account that `The pthread_exit() function cannot return to its
caller.`, so 3 lines below `pthread_exit(NULL);` will never be executed.
Which could be as intended. I would need to look at the test driver to see
what the expected behavior is.
>2. pthread_exit just terminate the calling thread, but the program will
terminate too if this is the last thread in the calling process
That is the NuttX behavior, but I don't think it is the Linux behavior. I
don't have good references but there is this stackoverflow response:
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
int main(int argc, char *argv[])
{
printf("-one-\n");
pthread_exit(NULL);
printf("-two-\n");
}
According to the post, the program never terminates, it simply freezes. The
first printf is printed , but the second one is not .

"It's fine to use pthread_exit in main. When pthread_exit is used, the main
thread will stop executing and will remain in zombie(defunct) status until all
other threads exit. ". Interesting discussion and more examples follow.
