I take this question of the The Linux Programming Interface:
I want someone to explain the under line statement because it sounds complex to me couldn't understand anything
30-1 Modify the program (thread_incr.c) so that each loop in the thread’s start function outputs the current value of glob and some identifier that uniquely identifies the thread.
Run the program, redirecting output to a file, and then inspect the
file to see what happens to glob as the kernel scheduler alternates execution between the
two threads.

pthread_create
PTHREAD_CREATE(3) Library Functions Manual PTHREAD_CREATE(3)NAME
pthread_create - create a new thread
SYNOPSIS
#include <pthread.h>
int pthread_create(pthread_t * thread, pthread_attr_t * attr, void * (*start_routine)(void *), void * arg);
DESCRIPTION
pthread_create creates a new thread of control that executes concurrently with the calling thread. The new thread applies the function
start_routine passing it arg as first argument. The new thread terminates either explicitly, by calling pthread_exit(3), or implicitly, by
returning from the start_routine function. The latter case is equivalent to calling pthread_exit(3) with the result returned by start_rou-
tine as exit code.
The attr argument specifies thread attributes to be applied to the new thread. See pthread_attr_init(3) for a complete list of thread
attributes. The attr argument can also be NULL, in which case default attributes are used: the created thread is joinable (not detached)
and has default (non real-time) scheduling policy.
RETURN VALUE
On success, the identifier of the newly created thread is stored in the location pointed by the thread argument, and a 0 is returned. On
error, a non-zero error code is returned.
ERRORS
EAGAIN not enough system resources to create a process for the new thread.
EAGAIN more than PTHREAD_THREADS_MAX threads are already active.
