socket_acc...closeonexec(3) Library Functions Manual socket_acc...closeonexec(3)

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 con-
     dition.

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);

SEE ALSO
     socket_accept4(3),  socket_connected(3),  socket_accept6_setcloseonexec(3),
     socket_accept4_makenonblocking_setcloseonexec(3)
