\&\s-1OPENSSL_VERSION_NUMBER\s0 is a numeric release version identifier:

.PP
|

.Vb 1
|

\& MMNNFFPPS: major minor fix patch status
|
|
.Ve
|
|
.PP
|
|
The status nibble has one of the values 0 for development, 1 to e for betas
|
|
1 to 14, and f for release.
|
|
.PP
|
|
for example
|
|
.PP
|
|
.Vb 3
|
|
\& 0x000906000 == 0.9.6 dev
|
|
\& 0x000906023 == 0.9.6b beta 3
|
|
\& 0x00090605f == 0.9.6e release
|
|
.Ve
|
|
.PP
|
|
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:
|
|
.PP
|
|
.Vb 1
|
|
\& MMNNFFRBB major minor fix final beta/patch
|
|
.Ve
|
|
.PP
|
|
for example
|
|
.PP
|
|
.Vb 2
|
|
\& 0x000904100 == 0.9.4 release
|
|
\& 0x000905000 == 0.9.5 dev
|
|
.Ve
|
|
.PP
|
|
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.
|
|
.PP
|
|
For backward compatibility, \s-1SSLEAY_VERSION_NUMBER\s0 is also defined.
|
|
.PP
|
|
\&\fISSLeay()\fR 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.
|
|
.PP

.IP "\s-1SSLEAY_VERSION\s0" 4
