OPENSSL_VERSION_NUMBER(3)   OpenSSL   OPENSSL_VERSION_NUMBER(3)





NAME
       OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version - get
       OpenSSL version number

SYNOPSIS
        #include <openssl/opensslv.h>
        #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL

        #include <openssl/crypto.h>
        long SSLeay(void);
        const char *SSLeay_version(int t);

DESCRIPTION
       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 develop-
       ment, 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.  Ver-
       sions 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 ver-
       sion 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 "com-
           piler: 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.

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

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

RETURN VALUE
       The version number.

HISTORY
       SSLeay() and SSLEAY_VERSION_NUMBER are available in all
       versions of SSLeay and OpenSSL.  OPENSSL_VERSION_NUMBER
       is available in all versions of OpenSSL.  SSLEAY_DIR was
       added in OpenSSL 0.9.7.
