OPENSSL_VERSION_NUMBER is a numeric release version identifier:
MMNNFFPPS: 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.
for example
0x000906000 == 0.9.6 dev
0x000906023 == 0.9.6b beta 3
0x00090605f == 0.9.6e release
Versions prior to 0.9.3 have identifiers < 0x0930. Versions
between 0.9.3 and 0.9.5 had a version identifier
with this interpretation:
MMNNFFRBB major minor fix final beta/patch
for example
0x000904100 == 0.9.4 release
0x000905000 == 0.9.5 dev
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.
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 t:
SSLEAY_VERSION
The text variant of the version number and the release
date. For example, "OpenSSL 0.9.5a 1 Apr 2000".
SSLEAY_CFLAGS
The compiler flags set for the compilation process in
the form "compiler: ..." if available or "compiler:
information not available" otherwise.
SSLEAY_BUILT_ON
The date of the build process in the form "built on:
..." if available or "built on: date not available"
otherwise.
SSLEAY_PLATFORM
The "Configure" target of the library build in the
form "platform: ..." if available or "platform:
information not available" otherwise.
For an unknown t, the text "not available" is returned.
The version number.

SSLeay() and SSLEAY_VERSION_NUMBER are available in all
versions of SSLeay and OpenSSL. OPENSSL_VERSION_NUMBER is
available in all versions of OpenSSL.
