| =head1 NAME |
| |
| OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version - get OpenSSL version number |
| |
| =head1 SYNOPSIS |
| |
| #include <openssl/opensslv.h> |
| #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL |
| |
| #include <openssl/crypto.h> |
| long SSLeay(void); |
| const char *SSLeay_version(int t); |
| |
| =head1 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 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 E<lt> 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 compared 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 B<t>: |
| |
| =over 4 |
| |
| =item SSLEAY_VERSION |
| |
| The text variant of the version number and the release date. For example, |
| "OpenSSL 0.9.5a 1 Apr 2000". |
| |
| =item SSLEAY_CFLAGS |
| |
| The compiler flags set for the compilation process in the form |
| "compiler: ..." if available or "compiler: information not available" |
| otherwise. |
| |
| =item SSLEAY_BUILT_ON |
| |
| The date of the build process in the form "built on: ..." if available |
| or "built on: date not available" otherwise. |
| |
| =item SSLEAY_PLATFORM |
| |
| The "Configure" target of the library build in the form "platform: ..." |
| if available or "platform: information not available" otherwise. |
| |
| =item SSLEAY_DIR |
| |
| The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "..."" |
| if available or "OPENSSLDIR: N/A" otherwise. |
| |
| =back |
| |
| For an unknown B<t>, the text "not available" is returned. |
| |
| =head1 RETURN VALUE |
| |
| The version number. |
