While stereotyped repetitions are frowned upon in literature, they serve a useful purpose in manual pages, because it is easier for the user to find certain information if it is always presented in the same way. For that reason, this commit harmonizes the varying formulations in the HISTORY section about which functions, flags, etc. were added in which OpenSSL version. It also attempts to make the pod files more grep friendly by avoiding to insert line breaks between the symbol names and the corresponding version number in which they were introduced (wherever possible). Some punctuation and typographical errors were fixed on the way. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7854)

=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
|
|

|
|
|
The value of B<OPENSSL_VERSION_TEXT>

|
|
|

|
|
"compiler: ..." if available or "compiler: information not available"
|

otherwise.

|
|
|
=item OPENSSL_DIR
|
|
|
|

|
|
|
|
=item OPENSSL_ENGINES_DIR
|
|

|
|
if available or "ENGINESDIR: N/A" otherwise.
|
|
|
|
=back
|
|
|
|
For an unknown B<t>, the text "not available" is returned.
|
|
|
|
=head1 BACKWARD COMPATIBILITY
|
|
|
|
For compatibility, some older macros and functions are retained or
|
|
synthesised.
|
|
They are all considered deprecated.
|
|
|
|
=head2 Macros
|
|
|
|
B<OPENSSL_VERSION_NUMBER> is a combination of the major, minor and
|
|
patch version into a single integer 0xMNN00PP0L, where:
|
|
|
|
=over 4
|
|
|
|
=item M
|
|
|
|
is the number from B<OPENSSL_VERSION_MAJOR>, in hexadecimal notation
|
|
|
|
=item NN
|
|
|
|
is the number from B<OPENSSL_VERSION_MINOR>, in hexadecimal notation
|
|
|
|
=item PP
|
|
|
|
is the number from B<OPENSSL_VERSION_PATCH>, in hexadecimal notation
|
|
|
|
=back
|
|
|
|
=head2 Functions
|
|
|
|
OpenSSL_version_num() returns the value of B<OPENSSL_VERSION_NUMBER>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
OPENSSL_version_major(), OPENSSL_version_minor() and OPENSSL_version_patch()
|
|
return the version number parts as integers.
|
|
|
|
OPENSSL_version_pre_release() and OPENSSL_version_build_metadata() return
|
|
the values of B<OPENSSL_VERSION_PRE_RELEASE> and
|
|
B<OPENSSL_VERSION_BUILD_METADATA> respectively as constant strings.
|
|
For any of them that is undefined, the empty string is returned.
|
|
|
|
OpenSSL_version() returns constant strings.
