134 OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version \- get OpenSSL version number
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/opensslv.h>
139 \& #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
143 \& #include <openssl/crypto.h>
144 \& long SSLeay(void);
145 \& const char *SSLeay_version(int t);
148 .IX Header "DESCRIPTION"
149 \&\s-1OPENSSL_VERSION_NUMBER\s0 is a numeric release version identifier:
152 \& MMNNFFPPS: major minor fix patch status
155 The status nibble has one of the values 0 for development, 1 to e for betas
156 1 to 14, and f for release.
161 \& 0x000906000 == 0.9.6 dev
162 \& 0x000906023 == 0.9.6b beta 3
163 \& 0x00090605f == 0.9.6e release
166 Versions prior to 0.9.3 have identifiers < 0x0930.
167 Versions between 0.9.3 and 0.9.5 had a version identifier with this
171 \& MMNNFFRBB major minor fix final beta/patch
177 \& 0x000904100 == 0.9.4 release
178 \& 0x000905000 == 0.9.5 dev
181 Version 0.9.5a had an interim interpretation that is like the current one,
182 except the patch level got the highest bit set, to keep continuity. The
183 number was therefore 0x0090581f.
185 For backward compatibility, \s-1SSLEAY_VERSION_NUMBER\s0 is also defined.
187 \&\fISSLeay()\fR returns this number. The return value can be compared to the
188 macro to make sure that the correct version of the library has been
189 loaded, especially when using DLLs on Windows systems.
191 \&\fISSLeay_version()\fR returns different strings depending on \fBt\fR:
192 .IP "\s-1SSLEAY_VERSION\s0" 4
193 .IX Item "SSLEAY_VERSION"
194 The text variant of the version number and the release date. For example,
195 \&\*(L"OpenSSL 0.9.5a 1 Apr 2000\*(R".
196 .IP "\s-1SSLEAY_CFLAGS\s0" 4
197 .IX Item "SSLEAY_CFLAGS"
198 The compiler flags set for the compilation process in the form
199 \&\*(L"compiler: ...\*(R" if available or \*(L"compiler: information not available\*(R"
201 .IP "\s-1SSLEAY_BUILT_ON\s0" 4
202 .IX Item "SSLEAY_BUILT_ON"
203 The date of the build process in the form \*(L"built on: ...\*(R" if available
204 or \*(L"built on: date not available\*(R" otherwise.
205 .IP "\s-1SSLEAY_PLATFORM\s0" 4
206 .IX Item "SSLEAY_PLATFORM"
207 The \*(L"Configure\*(R" target of the library build in the form \*(L"platform: ...\*(R"
208 if available or \*(L"platform: information not available\*(R" otherwise.
209 .IP "\s-1SSLEAY_DIR\s0" 4
210 .IX Item "SSLEAY_DIR"
211 The \*(L"\s-1OPENSSLDIR\s0\*(R" setting of the library build in the form \*(L"\s-1OPENSSLDIR:\s0 \*(R"..."\*(L"
212 if available or \*(R"\s-1OPENSSLDIR:\s0 N/A" otherwise.
214 For an unknown \fBt\fR, the text \*(L"not available\*(R" is returned.
216 .IX Header "RETURN VALUE"
219 .IX Header "SEE ALSO"
223 \&\fISSLeay()\fR and \s-1SSLEAY_VERSION_NUMBER\s0 are available in all versions of SSLeay and OpenSSL.
224 \&\s-1OPENSSL_VERSION_NUMBER\s0 is available in all versions of OpenSSL.
225 \&\fB\s-1SSLEAY_DIR\s0\fR was added in OpenSSL 0.9.7.
