Damian Hobson-Garcia 9e1a8b5ecc Attribute certificate getter and setter API
Only fields that are allowed by RFC 5755 are
accessible through this API.  Fields that are only supported
in version 1 attribute certificates (e.g. the AttCertIssuer
v1Form fields) are not implemented.

=head1 NAME
X509_get_serialNumber,
X509_get0_serialNumber,
X509_set_serialNumber,
X509_ACERT_get0_serialNumber,
X509_ACERT_set1_serialNumber
- get or set certificate serial number
=head1 SYNOPSIS
#include <openssl/x509.h>
ASN1_INTEGER *X509_get_serialNumber(X509 *x);
const ASN1_INTEGER *X509_get0_serialNumber(const X509 *x);
int X509_set_serialNumber(X509 *x, ASN1_INTEGER *serial);
#include <openssl/x509_acert.h>
ASN1_INTEGER *X509_ACERT_get0_serialNumber(X509_ACERT *x);
int X509_ACERT_set1_serialNumber(X509_ACERT *x, ASN1_INTEGER *serial);
=head1 DESCRIPTION
X509_get_serialNumber() returns the serial number of certificate B<x> as an
B<ASN1_INTEGER> structure which can be examined or initialised. The value
returned is an internal pointer which B<MUST NOT> be freed up after the call.
X509_get0_serialNumber() is the same as X509_get_serialNumber() except it
accepts a const parameter and returns a const result.
X509_set_serialNumber() sets the serial number of certificate B<x> to
B<serial>. A copy of the serial number is used internally so B<serial> should
be freed up after use.
X509_ACERT_get0_serialNumber() performs the same operation as
X509_get_serialNumber() for attribute certificates.
X509_ACERT_set1_serialNumber() performs the same operation as
X509_set_serialNumber() for attribute certificates.
=head1 RETURN VALUES
X509_get_serialNumber(), X509_get0_serialNumber() and
X509_ACERT_get0_serialNumber() return a pointer to an B<ASN1_INTEGER> structure.
X509_set_serialNumber() and X509_ACERT_set1_serialNumber() return 1 for success
and 0 for failure.
