|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn sctp_getaddrlen
|
|
returns the size of a specific address family. 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.
|
