.SH "NAME"

.SH "LIBRARY"

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\s-1OPENSSL_VERSION_NUMBER\s0 is a numeric release version identifier:
.PP
.Vb 1
\& MMNNFFPPS: major minor fix patch status
.Ve
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
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
for example
.PP
.Vb 2
\& 0x000904100 == 0.9.4 release
\& 0x000905000 == 0.9.5 dev
.Ve
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
\&\fISSLeay_version()\fR returns different strings depending on \fBt\fR:
.if n .Ip "\s-1SSLEAY_VERSION\s0 The text variant of the version number and the release date.  For example, """"OpenSSL 0.9.5a 1 Apr 2000""""." 4
.el .Ip "\s-1SSLEAY_VERSION\s0 The text variant of the version number and the release date.  For example, ``OpenSSL 0.9.5a 1 Apr 2000''." 4
.IX Item "SSLEAY_VERSION The text variant of the version number and the release date.  For example, "OpenSSL 0.9.5a 1 Apr 2000."
.Ip "\s-1SSLEAY_CFLAGS\s0 The flags given to the C compiler when compiling OpenSSL are returned in a string." 4
.IX Item "SSLEAY_CFLAGS The flags given to the C compiler when compiling OpenSSL are returned in a string."
.Ip "\s-1SSLEAY_PLATFORM\s0 The platform name used when OpenSSL was configured is returned." 4
.IX Item "SSLEAY_PLATFORM The platform name used when OpenSSL was configured is returned."
.PP
If the data request isn't available, a text saying that the information is
not available is returned.
.PP
For an unknown \fBt\fR, the text \*(L"not available\*(R" is returned.
.SH "RETURN VALUE"

\&\fISSLeay()\fR and \s-1SSLEAY_VERSION_NUMBER\s0 are available in all versions of SSLeay and OpenSSL.
