=head1 NAME
OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version - get OpenSSL version number
OPENSSL_VERSION_NUMBER, OPENSSL_VERSION_TEXT, SSLeay, SSLeay_version
- get OpenSSL version number
=head1 SYNOPSIS
#include <openssl/opensslv.h>
#define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
#define OPENSSL_VERSION_TEXT "OpenSSL x.y.z xx XXX xxxx"
#include <openssl/crypto.h>
long SSLeay(void);
@ -43,9 +45,12 @@ Version 0.9.5a had an interim interpretation that is like the current one,
except the patch level got the highest bit set, to keep continuity. The
number was therefore 0x0090581f.
For backward compatibility, SSLEAY_VERSION_NUMBER is also defined.
OPENSSL_VERSION_TEXT is the text variant of the version number and the
release date. For example,
"OpenSSL 1.0.1a 15 Oct 2015".
SSLeay() returns this number. The return value can be compared to the
macro to make sure that the correct version of the library has been
loaded, especially when using DLLs on Windows systems.
