-OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version - get OpenSSL version number

=head1 SYNOPSIS
#define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
#include <openssl/crypto.h>

=head1 DESCRIPTION
OPENSSL_VERSION_NUMBER is a numeric release version identifier:
- MMNNFFPPS: major minor fix patch status
+ MNNFFPPS: major minor fix patch status
The status nibble has one of the values 0 for development, 1 to e for betas
1 to 14, and f for release.
except the patch level got the highest bit set, to keep continuity. The
number was therefore 0x0090581f.
+OpenSSL_version_num() returns the version number.
-For backward compatibility, SSLEAY_VERSION_NUMBER is also defined.
-
-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.
-
-SSLeay_version() returns different strings depending on B<t>:
+OpenSSL_version() returns different strings depending on B<t>:
