This function is provided for application binary compatibility 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 .Fn getsockopt call fails, an error will be returned with .Va 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 function can return the following errors: l -tag -width Er t Bq Er EINVAL The address family specified does NOT exist. .El .Sh SEE ALSO .Xr getsockopt 2 , .Xr socket 2 , .Xr sctp 4
