SCTP

Stream Control Transmission Protocol

Synopsis:

#include <sys/socket.h>
#include <netinet/in.h>

int socket( PF_INET, 
            SOCK_DGRAM, 
            IPPROTO_SCTP);
	    
Or,
	    
int socket( PF_INET,
            SOCK_STREAM,
            IPPROTO_SCTP);
	    

Description:

The SCTP protocol provides a reliable, end-to-end message transport service. It has the following features:

• acknowledged error-free nonduplicated transfer of user data
• data fragmentation to conform to path MTU size
• sequenced delivery of user messages within multiple streams
• multi-homing
• protection against Denial of Service (DOS) attacks.

Returns:

A descriptor referencing the socket, or -1 if an error occurs (errno is set).

Errors:

EACCES

Permission to create a socket of the specified type and/or protocol is denied.

EMFILE

The per-process descriptor table is full.

ENFILE

The system file table is full.

ENOBUFS

Insufficient buffer space available. The socket can't be created until sufficient resources are freed.

ENOMEM

Not enough memory.

EPROTONOSUPPORT

The protocol type or the specified protocol isn't supported within this domain.
