48 Macros
49 The three macros OPENSSL_VERSION_MAJOR, OPENSSL_VERSION_MINOR and
50 OPENSSL_VERSION_PATCH represent the three parts of a version
51 identifier, MAJOR.MINOR.PATCH.
52 The macro OPENSSL_VERSION_PRE_RELEASE is an added bit of text that
54 indicates that this is a pre-release version, such as "-dev" for an
55 ongoing development snapshot or "-alpha3" for an alpha release. The
56 value must be a string.
57 The macro OPENSSL_VERSION_BUILD_METADATA is extra information, reserved
59 for other parties, such as "+fips", or "+vendor.1"). The OpenSSL
60 project will not touch this macro (will leave it an empty string). The
61 value must be a string.
62 OPENSSL_VERSION_STR is a convenience macro to get the short version
64 identifier string, "MAJOR.MINOR.PATCH".
65 OPENSSL_FULL_VERSION_STR is a convenience macro to get the longer
67 version identifier string, which combines OPENSSL_VERSION_STR,
68 OPENSSL_VERSION_PRE_RELEASE and OPENSSL_VERSION_BUILD_METADATA.
69 OPENSSL_VERSION_TEXT is a convenience macro to get a full descriptive
71 version text, which includes OPENSSL_FULL_VERSION_STR and the release
72 date.
73 OPENSSL_VERSION_PREREQ is a useful macro for checking whether the
75 OpenSSL version for the headers in use is at least at the given pre-
76 requisite major (maj) and minor (min) number or not. It will evaluate
77 to true if the header version number
78 (OPENSSL_VERSION_MAJOR.OPENSSL_VERSION_MINOR) is greater than or equal
79 to maj.min.
80 OPENSSL_VERSION_NUMBER is a combination of the major, minor and patch
82 version into a single integer 0xMNN00PP0L, where:
83 M is the number from OPENSSL_VERSION_MAJOR, in hexadecimal notation
85 NN is the number from OPENSSL_VERSION_MINOR, in hexadecimal notation
87 PP is the number from OPENSSL_VERSION_PATCH, in hexadecimal notation
89 Functions
91 OPENSSL_version_major(), OPENSSL_version_minor(),
92 OPENSSL_version_patch(), OPENSSL_version_pre_release(), and
93 OPENSSL_version_build_metadata() return the values of the macros above
94 for the build of the library, respectively.
95 OpenSSL_version() returns different strings depending on t:
97 OPENSSL_VERSION
99 The value of OPENSSL_VERSION_TEXT
100 OPENSSL_VERSION_STRING
102 The value of OPENSSL_VERSION_STR
103 OPENSSL_FULL_VERSION_STRING
105 The value of OPENSSL_FULL_VERSION_STR
106 OPENSSL_CFLAGS
108 The compiler flags set for the compilation process in the form
109 "compiler: ..." if available, or "compiler: information not
110 available" otherwise.
111 OPENSSL_BUILT_ON
113 The date of the build process in the form "built on: ..." if
114 available or "built on: date not available" otherwise. The date
115 would not be available in a reproducible build, for example.
116 OPENSSL_PLATFORM
118 The "Configure" target of the library build in the form "platform:
119 ..." if available, or "platform: information not available"
120 otherwise.
121 OPENSSL_DIR
123 The OPENSSLDIR setting of the library build in the form
124 "OPENSSLDIR: "..."" if available, or "OPENSSLDIR: N/A" otherwise.
125 OPENSSL_ENGINES_DIR
127 The ENGINESDIR setting of the library build in the form
128 "ENGINESDIR: "..."" if available, or "ENGINESDIR: N/A" otherwise.
129 This option is deprecated in OpenSSL 3.0.
130 OPENSSL_MODULES_DIR
132 The MODULESDIR setting of the library build in the form
133 "MODULESDIR: "..."" if available, or "MODULESDIR: N/A" otherwise.
134 OPENSSL_CPU_INFO
136 The current OpenSSL cpu settings. This is the current setting of
137 the cpu capability flags. It is usually automatically configured
138 but may be set via an environment variable. The value has the same
139 syntax as the environment variable. For x86 the string looks like
140 "CPUINFO: OPENSSL_ia32cap=0x123:0x456" or "CPUINFO: N/A" if not
141 available.
142 For an unknown t, the text "not available" is returned.
144 OPENSSL_info() also returns different strings depending on t:
146 OPENSSL_INFO_CONFIG_DIR
148 The configured "OPENSSLDIR", which is the default location for
149 OpenSSL configuration files.
150 OPENSSL_INFO_ENGINES_DIR
152 The configured "ENGINESDIR", which is the default location for
153 OpenSSL engines.
154 OPENSSL_INFO_MODULES_DIR
156 The configured "MODULESDIR", which is the default location for
157 dynamically loadable OpenSSL modules other than engines.
158 OPENSSL_INFO_DSO_EXTENSION
160 The configured dynamically loadable module extension.
161 OPENSSL_INFO_DIR_FILENAME_SEPARATOR
163 The separator between a directory specification and a filename.
164 Note that on some operating systems, this is not the same as the
165 separator between directory elements.
166 OPENSSL_INFO_LIST_SEPARATOR
168 The OpenSSL list separator. This is typically used in strings that
169 are lists of items, such as the value of the environment variable
170 $PATH on Unix (where the separator is ":") or "%PATH%" on Windows
171 (where the separator is ";").
172 OPENSSL_INFO_CPU_SETTINGS
174 The current OpenSSL cpu settings. This is the current setting of
175 the cpu capability flags. It is usually automatically configured
176 but may be set via an environment variable. The value has the same
177 syntax as the environment variable. For x86 the string looks like
178 "OPENSSL_ia32cap=0x123:0x456".
179 For an unknown t, NULL is returned.
181 OpenSSL_version_num() returns the value of OPENSSL_VERSION_NUMBER.
183
185 OPENSSL_version_major(), OPENSSL_version_minor() and
186 OPENSSL_version_patch() return the version number parts as integers.
187 OPENSSL_version_pre_release() and OPENSSL_version_build_metadata()
189 return the values of OPENSSL_VERSION_PRE_RELEASE and
190 OPENSSL_VERSION_BUILD_METADATA respectively as constant strings. For
191 any of them that is undefined, the empty string is returned.
192 OpenSSL_version() returns constant strings.

199 The macros and functions described here were added in OpenSSL 3.0,
200 except for OPENSSL_VERSION_NUMBER and OpenSSL_version_num().
