In addition to what achenle has already said:
- you are missing a ; after the call to getsockopt(),
- there is no : in a goto statement, and
- there is no label try_connect_again.

NAME
sctp_getaddrlen -- return the address length of an address family
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>

int
sctp_getaddrlen(sa_family_t family);
DESCRIPTION
The sctp_getaddrlen() function returns the size of a specific address family. 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 getsockopt() system calls. If for some reason a SCTP socket cannot be
created or the getsockopt() call fails, an error will be returned with errno set as specified in the socket() or getsockopt() system call.
RETURN VALUES
The call returns the number of bytes that the operating system expects for the specific address family or -1.
ERRORS
The sctp_getaddrlen() function can return the following errors:
[EINVAL] The address family specified does NOT exist.
