OPENSSL_VERSION_NUMBER(3) OpenSSL OPENSSL_VERSION_NUMBER(3)NAME
OPENSSL_VERSION_NUMBER, SSLeay SSLeay_version - get
OpenSSL version number
SYNOPSIS
#include <openssl/opensslv.h>
#define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
#include <openssl/crypto.h>
long SSLeay(void);
char *SSLeay_version(int t);
DESCRIPTIONOPENSSL_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 < 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 t:
26/Feb/2001 0.9.6 1
OPENSSL_VERSION_NUMBER(3) OpenSSL OPENSSL_VERSION_NUMBER(3)
SSLEAY_VERSION The text variant of the version number and
the release date. For example, """"OpenSSL 0.9.5a 1 Apr
2000"""".
SSLEAY_CFLAGS The flags given to the C compiler when
compiling OpenSSL are returned in a string.
SSLEAY_PLATFORM The platform name used when OpenSSL was
configured is returned.
If the data request isn't available, a text saying that
the information is not available is returned.
For an unknown t, the text "not available" is returned.
RETURN VALUE
The version number.
SEE ALSOcrypto(3)HISTORYSSLeay() and SSLEAY_VERSION_NUMBER are available in all
versions of SSLeay and OpenSSL. OPENSSL_VERSION_NUMBER is
available in all versions of OpenSSL.
