Re: 6.4 - How to use select routine

int sock_ready(sock) 
int sock; 
{ 
    int             res; 
    fd_set          sready; 
    struct timeval  nowait; 

    FD_ZERO(&sready); 
    FD_SET((unsigned int)sock,&sready); 
    /*bzero((char *)&nowait,sizeof(nowait));*/ 
    memset((char *)&nowait,0,sizeof(nowait)); 

    res = select(sock+1,&sready,NULL,NULL,&nowait); 
    if( FD_ISSET(sock,&sready) ) 
        res = 1; 
    else 
        res = 0; 

    return(res); 
}
