NAMEsctp_getaddrlen — return the address length of an address family
LIBRARYStandard C Library (libc, -lc)
SYNOPSIS#include < sys/types.h>

#include < netinet/sctp.h>
sctp_getaddrlen( sa_family_t family);
DESCRIPTIONThe 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 VALUESThe call returns the number of bytes that the operating system expects for the specific address family or -1.
ERRORSThe sctp_getaddrlen() function can return the following errors:
- [ EINVAL]
- The address family specified does NOT exist.
