If it is of type _SSSS_OOOO_CCCC_KKKK______DDDD_GGGG_RRRR_AAAA_MMMM, _cccc_oooo_nnnn_nnnn_eeee_cccc_tttt() specifies the peer with which the socket is to be associated; this address is the address to which datagrams are to be sent if a receiver is not explicitly designated; it is the only address from which datagrams are to be received. If the socket _s is of type _SSSS_OOOO_CCCC_KKKK______SSSS_TTTT_RRRR_EEEE_AAAA_MMMM, _cccc_oooo_nnnn_nnnn_eeee_cccc_tttt() attempts to make a connection to another socket. The other socket is specified by _n_a_m_e. _n_a_m_e is an address in the communications space of the socket. Each communications space interprets the _n_a_m_e parameter in its own way. If _s is not bound, then it will be bound to an address selected by the underlying transport provider. Generally, stream sockets may successfully _cccc_oooo_nnnn_nnnn_eeee_cccc_tttt() only once; datagram sockets may use _cccc_oooo_nnnn_nnnn_eeee_cccc_tttt() multiple times to change their association. Datagram sockets may dissolve the association by connecting to a null address. RRRREEEETTTTUUUURRRRNNNN VVVVAAAALLLLUUUUEEEE If the connection or binding succeeds, then 0 is returned. Otherwise a -1 is returned and a more specific error code is stored in _eeee_rrrr_rrrr_nnnn_oooo.

It is possible to _ssss_eeee_llll_eeee_cccc_tttt(3N) for completion by selecting the socket for writing. However, this is only possible if the socket STREAMS module is the topmost module on the protocol stack with a write service procedure. This will be the normal case. _EEEE_AAAA_LLLL_RRRR_EEEE_AAAA_DDDD_YYYY The socket is non-blocking and a previous connection attempt has not yet been completed. _EEEE_IIII_NNNN_TTTT_RRRR The connection attempt was interrupted before any data arrived by the delivery of a signal. _EEEE_NNNN_OOOO_TTTT_SSSS_OOOO_CCCC_KKKK The file referred to by _n_a_m_e is not a socket. _EEEE_PPPP_RRRR_OOOO_TTTT_OOOO_TTTT_YYYY_PPPP_EEEE The file referred to by _n_a_m_e is a socket of a type other than type _s (for example, _s is a _SSSS_OOOO_CCCC_KKKK______DDDD_GGGG_RRRR_AAAA_MMMM socket, while _n_a_m_e refers to a _SSSS_OOOO_CCCC_KKKK______SSSS_TTTT_RRRR_EEEE_AAAA_MMMM socket). _EEEE_NNNN_OOOO_SSSS_RRRR There were insufficient _SSSS_TTTT_RRRR_EEEE_AAAA_MMMM_SSSS resources available to complete the operation. The following errors are specific to connecting names in the UNIX domain. These errors may not apply in future versions of the UNIX IPC domain. _EEEE_NNNN_OOOO_TTTT_DDDD_IIII_RRRR A component of the path prefix of the pathname in _n_a_m_e is not a directory. _EEEE_NNNN_OOOO_EEEE_NNNN_TTTT A component of the path prefix of the pathname in _n_a_m_e does not exist. _EEEE_NNNN_OOOO_EEEE_NNNN_TTTT The socket referred to by the pathname in _n_a_m_e does not exist. _EEEE_AAAA_CCCC_CCCC_EEEE_SSSS Search permission is denied for a component of the path prefix of the pathname in _n_a_m_e. _EEEE_LLLL_OOOO_OOOO_PPPP Too many symbolic links were encountered in translating the pathname in _n_a_m_e. _EEEE_IIII_OOOO An I/O error occurred while reading from or writing to the file system.

UNIX domain sockets (address family _AAAA_FFFF______UUUU_NNNN_IIII_XXXX) require a _ssss_tttt_rrrr_uuuu_cccc_tttt _ssss_oooo_cccc_kkkk_eeee_tttt_aaaa_dddd_dddd_rrrr______uuuu_nnnn as defined in _ssss_yyyy_ssss_////_uuuu_nnnn_...._hhhh; Internet domain sockets (address family _AAAA_FFFF______IIII_NNNN_EEEE_TTTT) require a _ssss_tttt_rrrr_uuuu_cccc_tttt _ssss_oooo_cccc_kkkk_aaaa_dddd_dddd_rrrr______iiii_nnnn as defined in _nnnn_eeee_tttt_iiii_nnnn_eeee_tttt_////_iiii_nnnn_...._hhhh. Other address families may require other structures. Use the structure appropriate to the address family; cast the structure address to a generic _cccc_aaaa_dddd_dddd_rrrr______tttt in the call to _cccc_oooo_nnnn_nnnn_eeee_cccc_tttt() and pass the size of the structure in the _llll_eeee_nnnn_gggg_tttt_hhhh argument.
