my aim create server connected many clients (but rather limited number). clients running on mobile phones in lan. there can 2 mobile phones, can 10 mobile phones. wouldn't limit max number of phones ahead. i think tcp communication phone rather longer (not simple request/response rather longer dialog between both). thread pool seems better suited many connection, rather short request/response. i think best using simple pthreads . possibly create 1 pthread per 1 connection mobile phone . but here may doubts there can appear many such connections , number of pthreads large. think limiting number of connections example 10 @ same time , in order next mobile phone able connect such server there connected phone must disconnect. i have done this: int cs_fd; printf("waiting new connections on main thread...\n"); while(1) { cs_fd = accept_new_connection(ps_fd); if(cs_fd == failure) { fprintf(stderr, "accept_new_connect

are curly brackets suitable replacement other constructs?

[ -n "$test" ] && { echo this; false; } || { echo "this too?"; } your second example is should syntax error. nothing in documentation says can replace do / done pair compound command (which {...} is). update: i'm told maintainer of bash undocumented feature provides backwards compatibility undocumented feature in original bourne shell.
