.B #include <sxmp/sxmp.h>
.sp
sxlink_t *sxlink_master_accept(sxhub_t *hub, int sck, struct in_addr *addr);
sxlink_t *sxlink_connect(sxhub_t *hub, const char *host,
int port, const char *SSL_cert, const char *login,
const char *passwd);

.SH DESCRIPTION
.B sxlink_master_accept
will create a new link within
.B hub
hub with already accepted socket fd
.B sck
and set ip address of this connection pointed by
.B addr.
If
.B addr
is NULL, peer address will not set.
.br
.B sxlink_connect
will create a new link to the master side using
.B hub
hub to the host pointed via hostname or ip address in nul terminated string
.B host
running on port number
.B port
and send a X.509 certificate located on pathname pointed by
.B SSL_cert
trying to authorizated with username pointed by
.B login
and password pointed by
.B passwd
.br
.B sxlink_connect_at
will do the same as
.B sxlink_connect
but also will assign a private data pointed by
.B priv
to be used by application implementation.
.br
.B sxlink_close
will close link pointed by
.B co
destroying all allocated structures, including connection link itself.
.br
.SH RETURN VALUE
Upon successful completion, the functions
.B sxlink_master_accept
and
.B sxlink_connect
will return a valid pointer to the newly created link. Otherwise NULL will be returned and
.B errno will be set with appropriate error.
.B sxlink_close
will return
.B SXE_SUCCESS
on successful case, otherwise it will return an error described below.
.SH ERRORS
.B SXE_FAILED
will be returned in case of bad params given.
.br
.B SXE_ENOMEM
will be returned if there are no memory available.
.br
.B SXE_BADPROTO

.B SXE_EPERM
will be returned if permission was denied.
.br
.B SXE_LINKERROR
or
.B SXE_LINKBROKEN
