+=head1 NAME
+
+X509_get_version, X509_set_version, X509_REQ_get_version, X509_REQ_set_version,
+X509_CRL_get_version, X509_CRL_set_version - get or set certificate,
+certificate request or CRL version
+
+=head1 SYNOPSIS
+
+ #include <openssl/x509.h>
+
+ long X509_get_version(const X509 *x);
+ int X509_set_version(X509 *x, long version);
+
+ long X509_REQ_get_version(const X509_REQ *req);
+ int X509_REQ_set_version(X509_REQ *x, long version);
+
+ long X509_CRL_get_version(const X509_CRL *crl);
+ int X509_CRL_set_version(X509_CRL *x, long version);
+
+=head1 DESCRIPTION
+
+X509_get_version() returns the numerical value of the version field of
+certificate B<x>. Note: this is defined by standards (X.509 et al) to be one
+less than the certificate version. So a version 3 certificate will return 2 and
+a version 1 certificate will return 0.
+
+X509_set_version() sets the numerical value of the version field of certificate
+B<x> to B<version>.
+
+Similarly X509_REQ_get_version(), X509_REQ_set_version(),
+X509_CRL_get_version() and X509_CRL_set_version() get and set the version
+number of certificate requests and CRLs.
+
+=head1 NOTES
+
+The version field of certificates, certificate requests and CRLs has a
+DEFAULT value of B<v1(0)> meaning the field should be omitted for version
+1. This is handled transparently by these functions.
+
+=head1 RETURN VALUES
+
+X509_get_version(), X509_REQ_get_version() and X509_CRL_get_version()
+return the numerical value of the version field.
+
+X509_set_version(), X509_REQ_set_version() and X509_CRL_set_version()
+return 1 for success and 0 for failure.

+functions in OpenSSL 1.1.0, in previous versions they were macros.
