.TH socket_accept6 3
.SH NAME
socket_accept6 \- accept an IPv6 TCP connection on a socket
.SH SYNTAX
.B #include <libowfat/socket.h>

int \fBsocket_accept6\fP(int \fIs\fR,char \fIip\fR[16],uint16 *\fIport\fR,uint32 *\fIscope_id\fR);
.SH DESCRIPTION
When a TCP connection arrives on a listening TCP socket \fIs\fR, the
socket becomes readable.

socket_accept6 accepts the connection.  It sets \fIip\fR and \fIport\fR
to the client IP address and client TCP port and \fIscope_id\fR to the
IPv6 scope ID.  It creates a new socket for the connection, and returns
a file descriptor pointing to the new socket; you can use the read and
write system calls to transmit data through that file descriptor.

If \fIscope_id\fR is the null pointer, socket_accept6 will discard the
scope ID.

If something goes wrong, socket_accept6 returns -1, setting errno
appropriately, without creating a new socket.

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

  int \fIs\fR;
  char \fIip\fR[16];
  uint16 \fIport\fR;
  uint32 \fIscope_id\fR;

  \fIs\fR = socket_tcp6();
  socket_bind6(s,ip,port,scope_id);
  socket_listen(s,16);
  socket_accept6(s,ip,&port,&scope_id);
