20 OPENSSL_VERSION_NUMBER is a numeric release version identifier:
22 MNNFFPPS: major minor fix patch status
24 The status nibble has one of the values 0 for development, 1 to e for betas
25 1 to 14, and f for release.
29 0x000906000 == 0.9.6 dev
30 0x000906023 == 0.9.6b beta 3
31 0x00090605f == 0.9.6e release
33 Versions prior to 0.9.3 have identifiers E<lt> 0x0930.
34 Versions between 0.9.3 and 0.9.5 had a version identifier with this
37 MMNNFFRBB major minor fix final beta/patch
41 0x000904100 == 0.9.4 release
42 0x000905000 == 0.9.5 dev
44 Version 0.9.5a had an interim interpretation that is like the current one,
45 except the patch level got the highest bit set, to keep continuity. The
46 number was therefore 0x0090581f.
48 OpenSSL_version_num() returns the version number.
50 OpenSSL_version() returns different strings depending on B<t>:
56 The text variant of the version number and the release date. For example,
57 "OpenSSL 1.0.1a 15 Oct 2015".
61 The compiler flags set for the compilation process in the form
62 "compiler: ..." if available or "compiler: information not available"
65 =item OPENSSL_BUILT_ON
67 The date of the build process in the form "built on: ..." if available
68 or "built on: date not available" otherwise.
70 =item OPENSSL_PLATFORM
72 The "Configure" target of the library build in the form "platform: ..."
73 if available or "platform: information not available" otherwise.
77 The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "...""
78 if available or "OPENSSLDIR: N/A" otherwise.
80 =item OPENSSL_ENGINES_DIR
82 The "ENGINESDIR" setting of the library build in the form "ENGINESDIR: "...""
83 if available or "ENGINESDIR: N/A" otherwise.
87 For an unknown B<t>, the text "not available" is returned.
