There is no +known limit on the size of the created \s-1ASN1\s0 representation, so the necessary +amount of space should be obtained by first calling \fIi2d_SSL_SESSION()\fR with +\&\fBpp=NULL\fR, and obtain the size needed, then allocate the memory and +call \fIi2d_SSL_SESSION()\fR again. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fId2i_SSL_SESSION()\fR returns a pointer to the newly allocated \s-1SSL_SESSION\s0 +object.
