NAME

       socket_accept4_setcloseonexec - accept an IPv4 TCP connection on a socket and set it to close on exec

SYNTAX

       #include <libowfat/socket.h>

       int socket_accept4_setcloseonexec(int s,char ip[4],uint16 *port);

DESCRIPTION

       This is functionally equivalent to calling socket_accept4 and then calling io_closeonexec on the returned
       socket.

       However, if may save a syscall or two and in the process avoid a race condition.

EXAMPLE

         #include <libowfat/socket.h>

         int s;
         char ip[4];
         uint16 p;

         s = socket_tcp4();
         socket_bind4(s,ip,p);
         socket_listen(s,16);
         socket_accept4_setcloseonexec(s,ip,&p);
