OPENSSL_VERSION_NUMBER, SSLeay SSLeay_version − get OpenSSL version number
#include <openssl/opensslv.h> #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL #include <openssl/crypto.h> long SSLeay(void); char *SSLeay_version(int t);
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 flags given to the C compiler when
compiling OpenSSL
are returned in a string.
SSLEAY_PLATFORM The platform name used when OpenSSL
was configured is
returned.
If the data request isn’t available, a text saying that the information is not available is returned.
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.
