48 call binds or unbinds a address or a list of addresses to an
50 This allows a user to bind a subset of
54 call operates similarly to
56 but allows a list of addresses and also allows a bind or an
60 must be a valid SCTP socket descriptor.
63 is a list of addresses (where the list may be only 1 in
64 length) that the user wishes to bind or unbind to the
68 must be one of the following values.
70 .Dv SCTP_BINDX_ADD_ADDR
71 This value indicates that the listed address(es) need to
72 be added to the endpoint.
74 .Dv SCTP_BINDX_REM_ADDR
75 This value indicates that the listed address(es) need to
76 be removed from the endpoint.
78 Note that when a user adds or deletes an address to an
79 association if the dynamic address flag
80 .Va net.inet.sctp.auto_asconf
81 is enabled any associations in the endpoint will attempt to
82 have the address(es) added dynamically to the existing
85 The call returns 0 on success and -1 upon failure.
89 function can return the following errors:
92 This value is returned if the
94 field is not one of the allowed values (see above).
96 This value is returned if the number of addresses
97 being added causes a memory allocation failure in
102 is not a valid descriptor.
