OpenSSL_version(OPENSSL_DIR) gives you a nicely formatted string for display, but if all you really want is the directory itself, you were forced to parsed the string. This introduces a new function to get diverse configuration data from the library, OPENSSL_info(). This works the same way as OpenSSL_version(), but has its own series of types, currently including: OPENSSL_INFO_CONFIG_DIR returns OPENSSLDIR OPENSSL_INFO_ENGINES_DIR returns ENGINESDIR OPENSSL_INFO_MODULES_DIR returns MODULESDIR OPENSSL_INFO_DSO_EXTENSION returns DSO_EXTENSION OPENSSL_INFO_DIR_FILENAME_SEPARATOR returns directory/filename separator OPENSSL_INFO_LIST_SEPARATOR returns list separator For scripting purposes, this also adds the command 'openssl info'.

=head1 DESCRIPTION
|
|
|
|
=head2 Macros
|
|
|
|
The three macros B<OPENSSL_VERSION_MAJOR>, B<OPENSSL_VERSION_MINOR> and
|
|
B<OPENSSL_VERSION_PATCH> represent the three parts of a 3 numbered version
|
|
number, MAJOR.MINOR.PATCH.
|
|
|
|
The macro B<OPENSSL_VERSION_PRE_RELEASE> is an added bit of text that,
|
|
when defined, indicates that this is a pre-release version, such as
|
|
C<"-dev"> for an ongoing development snapshot, C<"-alpha3"> for an
|
|
alpha release, etc...
|
|
The value must be a string.
|
|
|
|
The macro B<OPENSSL_VERSION_BUILD_METADATA> is extra metadata, reserved
|
|
for other parties (examples: C<"+fips">, C<"+vendor.1">).
|
|
The OpenSSL project will not touch this macro.
|
|
The value must be a string.
|
|
|
|
B<OPENSSL_VERSION_STR> is a convenience macro to get the short version
|
|
number string, "MAJOR.MINOR.PATCH".
|
|
|
|
B<OPENSSL_FULL_VERSION_STR> is a convenience macro to get the longer
|
|
version number string, which combines B<OPENSSL_VERSION_STR>,
|
|
B<OPENSSL_VERSION_PRE_RELEASE> and B<OPENSSL_VERSION_BUILD_METADATA>.
|
|
|
|
B<OPENSSL_VERSION_TEXT> is a convenience macro to get a full descriptive
|
|
version text, which includes B<OPENSSL_FULL_VERSION_STR> and the release
|
|
date.
|
|
|
|
=head2 Functions
|
|
|
|
OPENSSL_version_major(), OPENSSL_version_minor(), OPENSSL_version_patch(),
|
|
OPENSSL_version_pre_release(), and OPENSSL_version_build_metadata() return
|
|
the values of the macros above for the build of the library, respectively.
|
|
|
|
OpenSSL_version() returns different strings depending on B<t>:
|
|
|
|
=over 4
|
|
|
|
=item OPENSSL_VERSION
|
|
|
|
The value of B<OPENSSL_VERSION_TEXT>
|
|
|
|
=item OPENSSL_VERSION_STRING
|
|
|
|
The value of B<OPENSSL_VERSION_STR>
|
|
|
|
=item OPENSSL_FULL_VERSION_STRING
|
|
|
|
The value of B<OPENSSL_FULL_VERSION_STR>
|
|
|
|
=item OPENSSL_CFLAGS
|
|
|
|
The compiler flags set for the compilation process in the form
|
|
"compiler: ..." if available or "compiler: information not available"
|
|
otherwise.
|
|
|
|
=item OPENSSL_BUILT_ON
|
|
|
|
The date of the build process in the form "built on: ..." if available
|
|
or "built on: date not available" otherwise.
|
|
|
|
=item OPENSSL_PLATFORM
|
|
|
|
The "Configure" target of the library build in the form "platform: ..."
|
|
if available or "platform: information not available" otherwise.
|
|
|
|
=item OPENSSL_DIR
|
|
|
|
The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "...""
|
|
if available or "OPENSSLDIR: N/A" otherwise.
|
|
|
|
=item OPENSSL_ENGINES_DIR
|
|
|
|
The "ENGINESDIR" setting of the library build in the form "ENGINESDIR: "...""
|
|
if available or "ENGINESDIR: N/A" otherwise.
|
|
|
|
=back
|
|
|
|
For an unknown B<t>, the text "not available" is returned.
|
|
|
|
OPENSSL_info() also returns different strings depending on B<t>:
|
|
|
|
=over 4
|
|
|
|
=item OPENSSL_INFO_CONFIG_DIR
|
|
|
|
The configured C<OPENSSLDIR>, which is the default location for
|
|
OpenSSL configuration files.
|
|
|
|
=item OPENSSL_INFO_ENGINES_DIR
|
|
|
|
The configured C<ENGINESDIR>, which is the default location for
|
|
OpenSSL engines.
|
|
|
|
=item OPENSSL_INFO_MODULES_DIR
|
|
|
|

|
|
dynamically loadable OpenSSL modules other than engines.
|
|
|
|
=item OPENSSL_INFO_DSO_EXTENSION
|
|
|
|
The configured dynamically loadable module extension.
|
|
|
|
=item OPENSSL_INFO_DIR_FILENAME_SEPARATOR
|
|
|
|

|
|
Note that on some operating systems, this is not the same as the
|
|
separator between directory elements.
|
|
|
|
=item OPENSSL_INFO_LIST_SEPARATOR
|
|
|
|
The OpenSSL list separator.
|
|
This is typically used in strings that are lists of items, such as the
|
|
value of the environment variable C<$PATH> on Unix (where the
|
|
separator is ":") or C<%PATH%> on Windows (where the separator is
|
|
";").
|

|
|
=back

|
|
|
For an unknown B<t>, NULL is returned.
|
|
|
|
=head1 BACKWARD COMPATIBILITY
|
|
|
|
For compatibility, some older macros and functions are retained or
|
|
synthesised.
|
|
They are all considered deprecated.
|
|
|
|

|
|
|

|
|
|
=head1 RETURN VALUES
|
|
|
|
OPENSSL_version_major(), OPENSSL_version_minor() and OPENSSL_version_patch()
|
|
