sctp_getpaddrs3
Return a list of addresses to the caller
Usage
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int
sctp_getpaddrs(int s, sctp_assoc_t asocid, struct sockaddr **addrs);
int
sctp_getladdrs(int s, sctp_assoc_t asocid, struct sockaddr **addrs);
Library
Standard C Library (libc, -lc)
Overview
The sctp_getpaddrs() function is used to get the list of the peers addresses. The sctp_getladdrs() function is used to get the list of the local addresses. The association of interest is identified by the asocid argument. The addresses are returned in a newly allocated array of socket addresses returned in the argument addrs upon success.
After the caller is finished, the function sctp_freepaddrs() or sctp_freeladdrs() should be used to release the memory allocated by these calls.
Return values
The call returns -1 upon failure and a count of the number of addresses returned in addrs upon success.
Errors
The functions can return the following errors:
- [EINVAL]
-
An address listed has an invalid family or no addresses were provided.
- [ENOMEM]
-
The call cannot allocate memory to hold the socket addresses.
- [EBADF]
-
The argument s is not a valid descriptor.
- [ENOTSOCK]
-
The argument s is not a socket.
