=head1 NAME
|
|
|
|
OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version - get OpenSSL version number
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/opensslv.h>
|
|
#define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
|
|
|
|
#include <openssl/crypto.h>
|
|
long SSLeay(void);
|
|
const char *SSLeay_version(int t);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
OPENSSL_VERSION_NUMBER is a numeric release version identifier:
|
|
|
|
MMNNFFPPS: major minor fix patch status
|
|
|
|
The status nibble has one of the values 0 for development, 1 to e for betas
|
|
1 to 14, and f for release.
|
|
|
|
for example
|
|
|
|
0x000906000 == 0.9.6 dev
|
|
0x000906023 == 0.9.6b beta 3
|
|
0x00090605f == 0.9.6e release
|
|
|
|
Versions prior to 0.9.3 have identifiers E<lt> 0x0930.
|
|
Versions between 0.9.3 and 0.9.5 had a version identifier with this
|
|
interpretation:
|
|
|
|
MMNNFFRBB major minor fix final beta/patch
|
|
|
|
for example
|
|
|
|
0x000904100 == 0.9.4 release
|
|
0x000905000 == 0.9.5 dev
|
|
|
|
Version 0.9.5a had an interim interpretation that is like the current one,
|
|
except the patch level got the highest bit set, to keep continuity. The
|
|
number was therefore 0x0090581f.
|
|
|
|
|
|
For backward compatibility, SSLEAY_VERSION_NUMBER is also defined.
|
|
|
|
SSLeay() returns this number. The return value can be compared to the
|
|
macro to make sure that the correct version of the library has been
|
|
loaded, especially when using DLLs on Windows systems.
|
|
|
|
SSLeay_version() returns different strings depending on B<t>:
|
|
|
|
=over 4
|
|
|
|
=item SSLEAY_VERSION
|
|
|
|
The text variant of the version number and the release date. For example,
|
|
"OpenSSL 0.9.5a 1 Apr 2000".
|
|
|
|
=item SSLEAY_CFLAGS
|
|
|
|
The compiler flags set for the compilation process in the form
|
|
"compiler: ..." if available or "compiler: information not available"
|
|
otherwise.
|
|
|
|
=item SSLEAY_BUILT_ON
|
|
|
|
The date of the build process in the form "built on: ..." if available
|
|
or "built on: date not available" otherwise.
|
|
|
|
=item SSLEAY_PLATFORM
|
|
|
|
The "Configure" target of the library build in the form "platform: ..."
|
|
if available or "platform: information not available" otherwise.
|
|
|
|
=item SSLEAY_DIR
|
|
|
|
The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "...""
|
|
if available or "OPENSSLDIR: N/A" otherwise.
|
|
|
|
=back
|
|
|
|
For an unknown B<t>, the text "not available" is returned.
|
|
|
|
