MirOS Manual: OPENSSL_VERSION_NUMBER(3), SSLeay(3), SSLeay_version(3)


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 identif-
     ier:

      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 com-
     pared 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" oth-
         erwise.

     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 ver-
     sions of SSLeay and OpenSSL. OPENSSL_VERSION_NUMBER is
     available in all versions of OpenSSL. SSLEAY_DIR was added
     in OpenSSL 0.9.7.
