.TH socket_sctp4 3
.SH NAME
socket_sctp4 \- create a non-blocking SCTP/IP stream socket
.SH SYNTAX
.B #include <socket.h>
int \fBsocket_sctp4\fP();
.SH DESCRIPTION
socket_sctp4 creates a non-blocking SCTP/IP stream socket and returns a
file descriptor pointing to that socket. If something goes wrong,
socket_sctp4 returns -1, setting errno appropriately, without allocating
any resources.
.SH EXAMPLE
#include <socket.h>
int \fIs\fR;
char \fIip\fR[4];
uint16 \fIp\fR;
\fIs\fR = socket_sctp4();
socket_bind4(s,ip,p);
