Hi Rasmus, Thanks for reply. The requirement I was looking for is to read/write given only the file descriptor number. PHP-CGI binary is invoked by a webserver that runs in jail-directory and doesn't have access to the file path directory. So, it communicates with another daemon that opens a socket to that file and in turn passes the file descriptor alone. Can you please suggest if there is any API in PHP that serves this requirement [read/write to given file descriptor] Please let me know if I need to provide more information.
