5 OPENSSL_VERSION_NUMBER, OpenSSL_version - get OpenSSL version number

13 const char *OpenSSL_version(int t);
17 OPENSSL_VERSION_NUMBER is a numeric release version identifier:
19 MNNFFPPS: major minor fix patch status
21 The status nibble has one of the values 0 for development, 1 to e for betas
22 1 to 14, and f for release.
26 0x000906000 == 0.9.6 dev
27 0x000906023 == 0.9.6b beta 3
28 0x00090605f == 0.9.6e release
30 Versions prior to 0.9.3 have identifiers E<lt> 0x0930.
31 Versions between 0.9.3 and 0.9.5 had a version identifier with this
34 MMNNFFRBB major minor fix final beta/patch
38 0x000904100 == 0.9.4 release
39 0x000905000 == 0.9.5 dev
41 Version 0.9.5a had an interim interpretation that is like the current one,
42 except the patch level got the highest bit set, to keep continuity. The
43 number was therefore 0x0090581f.
46 For backward compatibility, OPENSSL_VERSION_NUMBER is also defined.
48 OpenSSL_version() returns different strings depending on B<t>:
54 The text variant of the version number and the release date. For example,
55 "OpenSSL 1.0.1a 15 Oct 2015".
59 The compiler flags set for the compilation process in the form
60 "compiler: ..." if available or "compiler: information not available"
63 =item OPENSSL_BUILT_ON
65 The date of the build process in the form "built on: ..." if available
66 or "built on: date not available" otherwise.
68 =item OPENSSL_PLATFORM
70 The "Configure" target of the library build in the form "platform: ..."
71 if available or "platform: information not available" otherwise.
75 The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "...""
76 if available or "OPENSSLDIR: N/A" otherwise.
80 For an unknown B<t>, the text "not available" is returned.
