51 The three macros B<OPENSSL_VERSION_MAJOR>, B<OPENSSL_VERSION_MINOR> and
52 B<OPENSSL_VERSION_PATCH> represent the three parts of a version
53 identifier, B<I<MAJOR>.I<MINOR>.I<PATCH>>.
55 The macro B<OPENSSL_VERSION_PRE_RELEASE> is an added bit of text that
56 indicates that this is a pre-release version, such as C<"-dev"> for an
57 ongoing development snapshot or C<"-alpha3"> for an alpha release.
58 The value must be a string.
60 The macro B<OPENSSL_VERSION_BUILD_METADATA> is extra information, reserved
61 for other parties, such as C<"+fips">, or C<"+vendor.1">).
62 The OpenSSL project will not touch this macro (will leave it an empty string).
63 The value must be a string.
65 B<OPENSSL_VERSION_STR> is a convenience macro to get the short version
66 identifier string, C<"I<MAJOR>.I<MINOR>.I<PATCH>">.
68 B<OPENSSL_FULL_VERSION_STR> is a convenience macro to get the longer
69 version identifier string, which combines B<OPENSSL_VERSION_STR>,
70 B<OPENSSL_VERSION_PRE_RELEASE> and B<OPENSSL_VERSION_BUILD_METADATA>.
72 B<OPENSSL_VERSION_TEXT> is a convenience macro to get a full descriptive
73 version text, which includes B<OPENSSL_FULL_VERSION_STR> and the release
78 OPENSSL_version_major(), OPENSSL_version_minor(), OPENSSL_version_patch(),
79 OPENSSL_version_pre_release(), and OPENSSL_version_build_metadata() return
80 the values of the macros above for the build of the library, respectively.
82 OpenSSL_version() returns different strings depending on I<t>:
88 The value of B<OPENSSL_VERSION_TEXT>
90 =item OPENSSL_VERSION_STRING
92 The value of B<OPENSSL_VERSION_STR>
94 =item OPENSSL_FULL_VERSION_STRING
96 The value of B<OPENSSL_FULL_VERSION_STR>
100 The compiler flags set for the compilation process in the form
101 C<compiler: ...> if available, or C<compiler: information not available>
104 =item OPENSSL_BUILT_ON
106 The date of the build process in the form C<built on: ...> if available
107 or C<built on: date not available> otherwise.
108 The date would not be available in a reproducible build, for example.
110 =item OPENSSL_PLATFORM
112 The "Configure" target of the library build in the form C<platform: ...>
113 if available, or C<platform: information not available> otherwise.
117 The B<OPENSSLDIR> setting of the library build in the form C<OPENSSLDIR: "...">
118 if available, or C<OPENSSLDIR: N/A> otherwise.
120 =item OPENSSL_ENGINES_DIR
122 The B<ENGINESDIR> setting of the library build in the form C<ENGINESDIR: "...">
123 if available, or C<ENGINESDIR: N/A> otherwise. This option is deprecated in
126 =item OPENSSL_MODULES_DIR
128 The B<MODULESDIR> setting of the library build in the form C<MODULESDIR: "...">
129 if available, or C<MODULESDIR: N/A> otherwise.
131 =item OPENSSL_CPU_INFO
133 The current OpenSSL cpu settings.
134 This is the current setting of the cpu capability flags. It is usually
135 automatically configured but may be set via an environment variable.
136 The value has the same syntax as the environment variable.
137 For x86 the string looks like C<CPUINFO: OPENSSL_ia32cap=0x123:0x456>
138 or C<CPUINFO: N/A> if not available.
142 For an unknown I<t>, the text C<not available> is returned.
144 OPENSSL_info() also returns different strings depending on I<t>:
148 =item OPENSSL_INFO_CONFIG_DIR
150 The configured C<OPENSSLDIR>, which is the default location for
151 OpenSSL configuration files.
153 =item OPENSSL_INFO_ENGINES_DIR
155 The configured C<ENGINESDIR>, which is the default location for
158 =item OPENSSL_INFO_MODULES_DIR
160 The configured C<MODULESDIR>, which is the default location for
161 dynamically loadable OpenSSL modules other than engines.
163 =item OPENSSL_INFO_DSO_EXTENSION
165 The configured dynamically loadable module extension.
167 =item OPENSSL_INFO_DIR_FILENAME_SEPARATOR
169 The separator between a directory specification and a filename.
170 Note that on some operating systems, this is not the same as the
171 separator between directory elements.
173 =item OPENSSL_INFO_LIST_SEPARATOR
175 The OpenSSL list separator.
176 This is typically used in strings that are lists of items, such as the
177 value of the environment variable C<$PATH> on Unix (where the
178 separator is C<:>) or C<%PATH%> on Windows (where the separator is
181 =item OPENSSL_INFO_CPU_SETTINGS
183 The current OpenSSL cpu settings.
184 This is the current setting of the cpu capability flags. It is usually
185 automatically configured but may be set via an environment variable.
186 The value has the same syntax as the environment variable.
187 For x86 the string looks like C<OPENSSL_ia32cap=0x123:0x456>.
191 For an unknown I<t>, NULL is returned.
193 =head1 BACKWARD COMPATIBILITY
195 For compatibility, some older macros and functions are retained or
197 They are all considered deprecated.
201 B<OPENSSL_VERSION_NUMBER> is a combination of the major, minor and
202 patch version into a single integer 0xMNN00PP0L, where:
208 is the number from B<OPENSSL_VERSION_MAJOR>, in hexadecimal notation
212 is the number from B<OPENSSL_VERSION_MINOR>, in hexadecimal notation
216 is the number from B<OPENSSL_VERSION_PATCH>, in hexadecimal notation
222 OpenSSL_version_num() returns the value of B<OPENSSL_VERSION_NUMBER>.
226 OPENSSL_version_major(), OPENSSL_version_minor() and OPENSSL_version_patch()
227 return the version number parts as integers.
229 OPENSSL_version_pre_release() and OPENSSL_version_build_metadata() return
230 the values of B<OPENSSL_VERSION_PRE_RELEASE> and
231 B<OPENSSL_VERSION_BUILD_METADATA> respectively as constant strings.
232 For any of them that is undefined, the empty string is returned.
234 OpenSSL_version() returns constant strings.
242 The macros and functions described here were added in OpenSSL 3.0,
243 with the exception of the L</BACKWARD COMPATIBILITY> ones.
