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.
