.Dd August 1, 2018 .Dt SCTP_GETPADDRS 3 .Os .Sh NAME .Nm sctp_getpaddrs , .Nm sctp_getladdrs .Nd return a list of addresses to the caller .Sh LIBRARY .Lb libc .Sh SYNOPSIS n sys/types.h n sys/socket.h n netinet/sctp.h .Ft int .Fn sctp_getpaddrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs" .Ft int .Fn sctp_getladdrs "int s" "sctp_assoc_t asocid" "struct sockaddr **addrs" .Sh DESCRIPTION The .Fn sctp_getpaddrs function is used to get the list of the peers addresses. The .Fn sctp_getladdrs function is used to get the list of the local addresses. The association of interest is identified by the .Fa asocid argument. The addresses are returned in a newly allocated array of socket addresses returned in the argument .Fa addrs upon success.
p After the caller is finished, the function .Xr sctp_freepaddrs 3 or .Xr sctp_freeladdrs 3 should be used to release the memory allocated by these calls. .Sh RETURN VALUES The call returns -1 upon failure and a count of the number of addresses returned in .Fa addrs upon success. .Sh ERRORS The functions can return the following errors: l -tag -width Er t Bq Er EBADF The argument .Fa s is not a valid descriptor. t Bq Er EINVAL An address listed has an invalid family or no addresses were provided. t Bq Er ENOMEM The call cannot allocate memory to hold the socket addresses. t Bq Er ENOTSOCK The argument .Fa s is not a socket. .El .Sh SEE ALSO .Xr getsockopt 2 , .Xr sctp_freeladdrs 3 , .Xr sctp_freepaddrs 3 , .Xr sctp 4 .Rs .%R RFC .%N 6458 .%T "Sockets API Extensions for the Stream Control Transmission Protocol (SCTP)" .%D December 2011 .Re .Sh HISTORY These functions first appeared in .Nx 9.0 .
