20. Event Communication Implementation process repeater mode call

• Run

•  

• Create event

   1  HANDLE event  [4 ] = {0 };//  event  

   

• Create thread

   Span style= "COLOR: #008080" >1  HANDLE hthread[3 ] = {0 }; //  represents thread  

   

• Create critical section

   critical_section CS; 

   

• Create chat buffer

   1  volatile  char  str[1024 ] = {0  }; //  represents the buffer for chat content
