=head1 DESCRIPTION
|
|
The X509 ASN1 allocation routines, allocate and free an
|
X509 structure, which represents an X509 certificate.
|
|
X509_new() allocates and initializes a X509 structure.
|
|
X509_free() frees up the B<X509> structure B<a>.
|
|
=head1 RETURN VALUES
|
|
If the allocation fails, X509_new() returns B<NULL> and sets an error
|
code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>.
|
Otherwise it returns a pointer to the newly allocated structure.
|
|
X509_free() returns no value.
