Hi, when I write the pthread_create() and pthread_join in this way, then the program is OK.
However, I require to design the architecture like
In my requirement, once some events or signals come, then a thread is created for handle it; if no events then no thread is created.
There's no reason to start a separate thread if all you're going to do is call pthread_join() and wait for it to finish.

pthread_attr_setdetachstate
PTHREAD_ATTR(3) BSD Library Functions Manual PTHREAD_ATTR(3)NAME
pthread_attr_getdetachstate, pthread_attr_setdetachstate -- thread attribute operations
SYNOPSIS
#include <pthread.h>
int
pthread_attr_getdetachstate(const pthread_attr_t *attr, int *detachstate);
int
pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);
DESCRIPTION
Thread attributes are used to specify parameters to pthread_create(). One attribute object can be used in multiple calls to
pthread_create(), with or without modifications between calls.
One of these thread attributes governs the creation state of the new thread. The new thread can be either created "detached" or "joinable".
The constants corresponding to these states are PTHREAD_CREATE_DETACHED and PTHREAD_CREATE_JOINABLE respectively. Creating a "joinable"
thread allows the user to call pthread_join() and pthread_detach(), with the new thread's ID. A "detached" thread's ID cannot be used with
pthread_join() and pthread_detach(). The default value for the "detachstate" attribute is PTHREAD_CREATE_JOINABLE.
The pthread_attr_setdetachstate() function sets the thread's "detachstate" attribute.
The "detachstate" attribute is set within the attr argument, which can subsequently be used as an argument to pthread_create().
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. pthread_attr_getdetachstate(), on
success, will copy the value of the thread's "detachstate" attribute to the location pointed to by the second function parameter.
ERRORS
pthread_attr_getdetachstate() will fail if:
[EINVAL] Invalid value for attr
pthread_attr_setdetachstate() will fail if:
[EINVAL] Invalid value for attr or detachstate.
