.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fISSL_new()\fR creates a new \fB\s-1SSL\s0\fR structure which is needed to hold the
data for a \s-1TLS/SSL\s0 connection. The new structure inherits the settings
of the underlying context \fBctx\fR: connection method,
options, verification settings, timeout settings. An \fB\s-1SSL\s0\fR structure is
reference counted. Creating an \fB\s-1SSL\s0\fR structure for the first time increments
the reference count. Freeing it (using SSL_free) decrements it. When the
reference count drops to zero, any memory or resources allocated to the \fB\s-1SSL\s0\fR
structure are freed.
.PP
\&\fISSL_up_ref()\fR increments the reference count for an
existing \fB\s-1SSL\s0\fR structure.
.PP
\&\fISSL_dup()\fR duplicates an existing \fB\s-1SSL\s0\fR structure into a new allocated one. All
settings are inherited from the original \fB\s-1SSL\s0\fR structure. Dynamic data (i.e.
existing connection details) are not copied, the new \fB\s-1SSL\s0\fR is set into an
initial accept (server) or connect (client) state.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The following return values can occur:
.IP "\s-1NULL\s0" 4
.IX Item "NULL"
The creation of a new \s-1SSL\s0 structure failed. Check the error stack to
find out the reason.
.IP "Pointer to an \s-1SSL\s0 structure" 4
.IX Item "Pointer to an SSL structure"
The return value points to an allocated \s-1SSL\s0 structure.
.Sp
\&\fISSL_up_ref()\fR returns 1 for success and 0 for failure.
