=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>: |
|

=item SSLEAY_VERSION |

|
=item SSLEAY_PLATFORM |
|
|
