.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.
