.TH socket_accept4_setcloseonexec 3
.SH NAME
socket_accept4_setcloseonexec \- accept an IPv4 TCP connection on a socket and set it to close on exec
.SH SYNTAX
.B #include <libowfat/socket.h>

int \fBsocket_accept4_setcloseonexec\fP(int \fIs\fR,char \fIip\fR[4],uint16 *\fIport\fR);
.SH DESCRIPTION
This is functionally equivalent to calling \fIsocket_accept4\fR and then
calling \fIio_closeonexec\fR on the returned socket.

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

.SH EXAMPLE
  #include <libowfat/socket.h>

  int \fIs\fR;
  char \fIip\fR[4];
  uint16 \fIp\fR;

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