=head1 DESCRIPTION
The X509 encode and decode routines encode and parse an
B<X509> structure, which represents an X509 certificate.
-d2i_X509() attempts to decode B<len> bytes at B<*out>. If
+d2i_X509() attempts to decode B<len> bytes at B<*in>. If
successful a pointer to the B<X509> structure is returned. If an error
occurred then B<NULL> is returned. If B<px> is not B<NULL> then the
returned structure is written to B<*px>. If B<*px> is not B<NULL>
then it is assumed that B<*px> contains a valid B<X509>
structure and an attempt is made to reuse it. If the call is
-successful B<*out> is incremented to the byte following the
+successful B<*in> is incremented to the byte following the
parsed data.
i2d_X509() encodes the structure pointed to by B<x> into DER format.
or B<NULL> if an error occurs. The error code that can be obtained by
L<ERR_get_error(3)|ERR_get_error(3)>.
-i2d_X509(), i2d_X509_bio() and i2d_X509_fp() return a the number of bytes

+i2d_X509() returns the number of bytes successfully encoded or a negative

-i2d_X509_bio() and i2d_X509_fp() returns 1 for success and 0 if an error
