NAME

       sctp_optinfo - Get options on a SCTP socket.

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_opt_info(int sd, sctp_assoc_t id, int opt,
			 void * arg, socklen_t * size);

DESCRIPTION

       sctp_opt_info  is a wrapper library function that can be used to get SCTP level options on a socket.  sd is the socket descriptor for which
       the option is requested. For one-to-many style sockets, id specifies the association to query. For one-to-one style sockets, id is ignored.
       opt  specifes  the  SCTP  socket option to get.	arg is an option-specific structure buffer provided by the caller.  size is a value-result
       parameter, initially containing the size of the buffer pointed to by arg and modifed on return to indicate the actual  size  of	the  value
       returned.

RETURN VALUE

       On success, sctp_opt_info returns 0 and on failure -1 is returned with errno set to the appropriate error code.

NAME

       sctp_recvmsg - Receive a message from a SCTP socket.

SYNOPSIS

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <netinet/sctp.h>

       int sctp_recvmsg(int sd, void * msg, size_t len,
			struct sockaddr * from, socklen_t * fromlen,
			struct sctp_sndrcvinfo * sinfo, int * msg_flags);

DESCRIPTION

       sctp_recvmsg  is  a wrapper library function that can be used to receive a message from a socket while using the advanced features of SCTP.
       sd is the socket descriptor on which the message pointed to by msg of length len is received.

       If from is not NULL, the source address of the message is filled in. The argument fromlen is a value-result parameter. initialized  to  the
       size of the buffer associated with from , and modified on return to indicate the actual size of the address stored.

       sinfo  is  a  pointer to a sctp_sndrcvinfo structure to be filled upon receipt of the message.  msg_flags is a pointer to a integer that is
       filled with any message flags like MSG_NOTIFICATION or MSG_EOR.

RETURN VALUE

       On success, sctp_recvmsg returns the number of bytes received or -1 if an error occurred.
