SCTP_OPT_INFO(3) Linux Programmer's Manual SCTP_OPT_INFO(3)
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 param-
eter, 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.
