52 call binds or unbinds a address or a list of addresses to an

60 but allows a list of addresses and also allows a bind or an
64 must be a valid SCTP socket descriptor.
67 is a list of addresses (where the list may be only 1 in
68 length) that the user wishes to bind or unbind to the
72 must be one of the following values.
74 .Dv SCTP_BINDX_ADD_ADDR
75 This value indicates that the listed address(es) need to
76 be added to the endpoint.
78 .Dv SCTP_BINDX_DEL_ADDR
79 This value indicates that the listed address(es) need to
80 be removed from the endpoint.
82 Note that when a user adds or deletes an address to an
83 association if the dynamic address flag
84 .Va net.inet.sctp.auto_asconf
85 is enabled any associations in the endpoint will attempt to
86 have the address(es) added dynamically to the existing
89 The call returns 0 on success and -1 upon failure.
93 function can return the following errors:
96 This value is returned if the
98 field is not one of the allowed values (see above).
100 This value is returned if the number of addresses
101 being added causes a memory allocation failure in
106 is not a valid descriptor.
