This function +is provided for application binary compatability since it +provides the application with the size the operating system +thinks the specific address family is. Note that the function +will actually create an SCTP socket and then gather the +information via a +.Fn getsockopt +system calls. If for some reason a SCTP socket cannot +be created or the getsockopt fails, an error will be returned +with errno set as specified in the +.Fn socket +or +.Fn getsockopt +system call. +.Sh RETURN VALUES +The call returns the number of bytes that the operating +system expects for the specific address family or -1. +.Sh ERRORS +The +.Fn sctp_getaddrlen +.Bl -tag -width Er +.It Bq Er EINVAL +The address family specified does NOT exist. +.El +.Sh SEE ALSO +.Xr sctp 4 , +.Xr socket 2 , +.Xr getsockopt 2 , + |
