NAME¶

socket_accept4_makenonblocking_setcloseonexec - accept an IPv4 TCP connection on a socket and set it to non-blocking I/O and close-on-exec #include <libowfat/socket.h>

int socket_accept4_makenonblocking_setcloseonexec(int s,char ip[4],uint16 *port);

DESCRIPTION¶

This is functionally equivalent to calling socket_accept4 and then calling ndelay_on and io_tcloseonexec 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_makenonblocking_setcloseonexec(s,ip,&p);
