53 The three macros B<OPENSSL_VERSION_MAJOR>, B<OPENSSL_VERSION_MINOR> and
54 B<OPENSSL_VERSION_PATCH> represent the three parts of a version
55 identifier, B<I<MAJOR>.I<MINOR>.I<PATCH>>.
57 The macro B<OPENSSL_VERSION_PRE_RELEASE> is an added bit of text that
58 indicates that this is a pre-release version, such as C<"-dev"> for an
59 ongoing development snapshot or C<"-alpha3"> for an alpha release.
60 The value must be a string.
62 The macro B<OPENSSL_VERSION_BUILD_METADATA> is extra information, reserved
63 for other parties, such as C<"+fips">, or C<"+vendor.1">).
64 The OpenSSL project will not touch this macro (will leave it an empty string).
65 The value must be a string.
67 B<OPENSSL_VERSION_STR> is a convenience macro to get the short version
68 identifier string, C<"I<MAJOR>.I<MINOR>.I<PATCH>">.
70 B<OPENSSL_FULL_VERSION_STR> is a convenience macro to get the longer
71 version identifier string, which combines B<OPENSSL_VERSION_STR>,
72 B<OPENSSL_VERSION_PRE_RELEASE> and B<OPENSSL_VERSION_BUILD_METADATA>.
74 B<OPENSSL_VERSION_TEXT> is a convenience macro to get a full descriptive
75 version text, which includes B<OPENSSL_FULL_VERSION_STR> and the release
78 B<OPENSSL_VERSION_PREREQ> is a useful macro for checking whether the OpenSSL
79 version for the headers in use is at least at the given pre-requisite major
80 (B<maj>) and minor (B<min>) number or not. It will evaluate to true if the
81 header version number (B<OPENSSL_VERSION_MAJOR>.B<OPENSSL_VERSION_MINOR>) is
82 greater than or equal to B<maj>.B<min>.
86 OPENSSL_version_major(), OPENSSL_version_minor(), OPENSSL_version_patch(),
87 OPENSSL_version_pre_release(), and OPENSSL_version_build_metadata() return
88 the values of the macros above for the build of the library, respectively.
90 OpenSSL_version() returns different strings depending on I<t>:
96 The value of B<OPENSSL_VERSION_TEXT>
98 =item OPENSSL_VERSION_STRING
100 The value of B<OPENSSL_VERSION_STR>
102 =item OPENSSL_FULL_VERSION_STRING
104 The value of B<OPENSSL_FULL_VERSION_STR>
108 The compiler flags set for the compilation process in the form
109 C<compiler: ...> if available, or C<compiler: information not available>
112 =item OPENSSL_BUILT_ON
114 The date of the build process in the form C<built on: ...> if available
115 or C<built on: date not available> otherwise.
116 The date would not be available in a reproducible build, for example.
118 =item OPENSSL_PLATFORM
120 The "Configure" target of the library build in the form C<platform: ...>
121 if available, or C<platform: information not available> otherwise.
125 The B<OPENSSLDIR> setting of the library build in the form C<OPENSSLDIR: "...">
126 if available, or C<OPENSSLDIR: N/A> otherwise.
128 =item OPENSSL_ENGINES_DIR
130 The B<ENGINESDIR> setting of the library build in the form C<ENGINESDIR: "...">
131 if available, or C<ENGINESDIR: N/A> otherwise. This option is deprecated in
134 =item OPENSSL_MODULES_DIR
136 The B<MODULESDIR> setting of the library build in the form C<MODULESDIR: "...">
137 if available, or C<MODULESDIR: N/A> otherwise.
139 =item OPENSSL_CPU_INFO
141 The current OpenSSL cpu settings.
142 This is the current setting of the cpu capability flags. It is usually
143 automatically configured but may be set via an environment variable.
144 The value has the same syntax as the environment variable.
145 For x86 the string looks like C<CPUINFO: OPENSSL_ia32cap=0x123:0x456>
146 or C<CPUINFO: N/A> if not available.
150 For an unknown I<t>, the text C<not available> is returned.
152 OPENSSL_info() also returns different strings depending on I<t>:
156 =item OPENSSL_INFO_CONFIG_DIR
158 The configured C<OPENSSLDIR>, which is the default location for
159 OpenSSL configuration files.
161 =item OPENSSL_INFO_ENGINES_DIR
163 The configured C<ENGINESDIR>, which is the default location for
166 =item OPENSSL_INFO_MODULES_DIR
168 The configured C<MODULESDIR>, which is the default location for
169 dynamically loadable OpenSSL modules other than engines.
171 =item OPENSSL_INFO_DSO_EXTENSION
173 The configured dynamically loadable module extension.
175 =item OPENSSL_INFO_DIR_FILENAME_SEPARATOR
177 The separator between a directory specification and a filename.
178 Note that on some operating systems, this is not the same as the
179 separator between directory elements.
181 =item OPENSSL_INFO_LIST_SEPARATOR
183 The OpenSSL list separator.
184 This is typically used in strings that are lists of items, such as the
185 value of the environment variable C<$PATH> on Unix (where the
186 separator is C<:>) or C<%PATH%> on Windows (where the separator is
189 =item OPENSSL_INFO_CPU_SETTINGS
191 The current OpenSSL cpu settings.
192 This is the current setting of the cpu capability flags. It is usually
193 automatically configured but may be set via an environment variable.
194 The value has the same syntax as the environment variable.
195 For x86 the string looks like C<OPENSSL_ia32cap=0x123:0x456>.
199 For an unknown I<t>, NULL is returned.
201 =head1 BACKWARD COMPATIBILITY
203 For compatibility, some older macros and functions are retained or
205 They are all considered deprecated.
209 B<OPENSSL_VERSION_NUMBER> is a combination of the major, minor and
210 patch version into a single integer 0xMNN00PP0L, where:
216 is the number from B<OPENSSL_VERSION_MAJOR>, in hexadecimal notation
220 is the number from B<OPENSSL_VERSION_MINOR>, in hexadecimal notation
224 is the number from B<OPENSSL_VERSION_PATCH>, in hexadecimal notation
230 OpenSSL_version_num() returns the value of B<OPENSSL_VERSION_NUMBER>.
234 OPENSSL_version_major(), OPENSSL_version_minor() and OPENSSL_version_patch()
235 return the version number parts as integers.
237 OPENSSL_version_pre_release() and OPENSSL_version_build_metadata() return
238 the values of B<OPENSSL_VERSION_PRE_RELEASE> and
239 B<OPENSSL_VERSION_BUILD_METADATA> respectively as constant strings.
240 For any of them that is undefined, the empty string is returned.
242 OpenSSL_version() returns constant strings.
250 The macros and functions described here were added in OpenSSL 3.0,
251 with the exception of the L</BACKWARD COMPATIBILITY> ones.
