=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 version
|
|
identifier, B<I<MAJOR>.I<MINOR>.I<PATCH>>.
|
|
|
|
The macro B<OPENSSL_VERSION_PRE_RELEASE> is an added bit of text that
|
|
indicates that this is a pre-release version, such as C<"-dev"> for an
|
|
ongoing development snapshot or C<"-alpha3"> for an alpha release.
|
|
The value must be a string.
|
|
|
|
The macro B<OPENSSL_VERSION_BUILD_METADATA> is extra information, reserved
|
|
for other parties, such as C<"+fips">, or C<"+vendor.1">).
|
|
The OpenSSL project will not touch this macro (will leave it an empty string).
|
|
The value must be a string.
|
|
|
|
B<OPENSSL_VERSION_STR> is a convenience macro to get the short version
|
|
identifier string, C<"I<MAJOR>.I<MINOR>.I<PATCH>">.
|
|
|
|
B<OPENSSL_FULL_VERSION_STR> is a convenience macro to get the longer
|
|
version identifier 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 I<t>:
|
|
|
|
=over 4
|
|
|
|
=item OPENSSL_VERSION
|
|
|
|
The value of B<OPENSSL_VERSION_TEXT>

|
|
|
|

|
|
|
|
=item OPENSSL_CFLAGS
|
|

|
|
|
=item OPENSSL_BUILT_ON
|
|
|
|
The date of the build process in the form C<built on: ...> if available
|
|
or C<built on: date not available> otherwise.
|
|
The date would not be available in a reproducible build, for example.
|
|
|
|
=item OPENSSL_PLATFORM
|
|
|
|
The "Configure" target of the library build in the form C<platform: ...>
|
|
if available, or C<platform: information not available> otherwise.
|
|
|
|
=item OPENSSL_DIR
|
|
|
|
The B<OPENSSLDIR> setting of the library build in the form C<OPENSSLDIR: "...">
|
|
if available, or C<OPENSSLDIR: N/A> otherwise.
|
|
|
|
=item OPENSSL_ENGINES_DIR
|
|
|
|
The B<ENGINESDIR> setting of the library build in the form C<ENGINESDIR: "...">
|
|
if available, or C<ENGINESDIR: N/A> otherwise. This option is deprecated in
|
|
OpenSSL 3.0.
|
|
|
|
=item OPENSSL_MODULES_DIR
|
|
|
|
The B<MODULESDIR> setting of the library build in the form C<MODULESDIR: "...">
|
|
if available, or C<MODULESDIR: N/A> otherwise.
|
|
|
|
=item OPENSSL_CPU_INFO
|
|
|
|
The current OpenSSL cpu settings.
|
|
This is the current setting of the cpu capability flags. It is usually
|
|
automatically configured but may be set via an environment variable.
|
|
The value has the same syntax as the environment variable.
|
|
For x86 the string looks like C<CPUINFO: OPENSSL_ia32cap=0x123:0x456>
|
|
or C<CPUINFO: N/A> if not available.
|
|
|
|
=back
|
|
|
|
For an unknown I<t>, the text C<not available> is returned.
|
|
|
|
OPENSSL_info() also returns different strings depending on I<t>:

|
OpenSSL configuration files.

|
|
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 C<:>) or C<%PATH%> on Windows (where the separator is
|
|
C<;>).
|
|
|
|
=item OPENSSL_INFO_CPU_SETTINGS
