OPENSSLVERSIONNUMBER(3) OpenSSL OPENSSLVERSIONNUMBER(3)

NAME
       OPENSSLVERSIONNUMBER, SSLeay, SSLeayversion - get OpenSSL version
       number

SYNOPSIS
        #include 
        #define OPENSSLVERSIONNUMBER 0xnnnnnnnnnL

        #include 
        long SSLeay(void);
        const char *SSLeayversion(int t);

DESCRIPTION
       OPENSSLVERSIONNUMBER 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, SSLEAYVERSIONNUMBER 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.

       SSLeayversion() returns different strings depending on tt:

       SSLEAYVERSION
           The text variant of the version number and the release date.  For
           example, "OpenSSL 0.9.5a 1 Apr 2000".

       SSLEAYCFLAGS
           The compiler flags set for the compilation process in the form
           "compiler: ..."  if available or "compiler: information not
           available" otherwise.

       SSLEAYBUILTON
           The date of the build process in the form "built on: ..." if
           available or "built on: date not available" otherwise.

       SSLEAYPLATFORM
           The "Configure" target of the library build in the form "platform:
           ..."  if available or "platform: information not available"
           otherwise.

       SSLEAYDIR
           The "OPENSSLDIR" setting of the library build in the form
           "OPENSSLDIR: "...""  if available or "OPENSSLDIR: N/A" otherwise.

       For an unknown tt, the text "not available" is returned.

RREETTUURRNN VVAALLUUEE
       The version number.

HISTORY       SSLeay() and SSLEAYVERSIONNUMBER are available in all versions of
       SSLeay and OpenSSL.  OPENSSLVERSIONNUMBER is available in all
       versions of OpenSSL.  SSSSLLEEAAYYDDIIRR was added in OpenSSL 0.9.7.
