#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);
Описание (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. The value of msg_flags pointer should be initialized to
0 to avoid unexpected behavior; msg_flags is also used as an
input flags argument to recvmsg function.
Возвращаемое значение (Return value)
On success, sctp_recvmsg returns the number of bytes received or
-1 if an error occurred.
