Chatting Server based on MultiThread

• One process can implements multitasking as using multithread.

 Use 'clnt_cnt, clnt_socks[]' valuables in critical section because of synchronization.

 Critical section is implemented by using 'mutex'

 - pthread_mutex_lock(&mutex) : critical section start

 - pthread_mutex_unlock(&mutex) : critical section end

• Thread Context Switching is faster than Process Context Switching

 thread share heap, data(static), code except for stack, register.
