These functions are used to examine stacks of extensions directly.
Applications that want to parse or encode and add an extension should
use the extension encode and decode functions instead, such as
X509_add1_ext_i2d() and X509_get_ext_d2i().
Extension indices start from zero, so a zero index return value is B<not> an
error. These search functions start from the extension B<after> the B<lastpos>
parameter so it should initially be set to B<-1>, if it is set to zero the
initial extension will not be checked.
=head1 BUGS
For X509v3_get_ext_by_NID(), X509v3_get_ext_by_OBJ(),
X509v3_get_ext_by_critical() and its variants, a zero index return value
is not an error since extension STACK I<x> indices start from zero.
These search functions start from the extension B<after> the I<lastpos> parameter
so it should initially be set to -1. If it is set to zero, the initial extension
will not be checked.
X509v3_delete_ext() and its variants are a bit counter-intuitive
because these functions do not free the extension they delete.
They return an B<X509_EXTENSION> object which must be explicitly freed
using X509_EXTENSION_free().
