.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);
.SH "SEE ALSO"
socket_accept4(3), socket_connected(3),
socket_accept6_setcloseonexec(3),
