OPENSSL_VERSION_NUMBER(3) OpenSSL OPENSSL_VERSION_NUMBER(3)

NAME

OPENSSL_VERSION_NUMBER, OpenSSL_version, OpenSSL_version_num - get OpenSSL version number

SYNOPSIS

 #include <openssl/opensslv.h>
 #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL
 #include <openssl/crypto.h>
 unsigned long OpenSSL_version_num();
 const char *OpenSSL_version(int t);

DESCRIPTION

OPENSSL_VERSION_NUMBER is a numeric release version identifier:
 MNNFFPPS: 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.
OpenSSL_version_num() returns the version number.
OpenSSL_version() returns different strings depending on t:
OPENSSL_VERSION
The text variant of the version number and the release date. For example, "OpenSSL 1.0.1a 15 Oct 2015".
OPENSSL_CFLAGS
The compiler flags set for the compilation process in the form "compiler: ..." if available or "compiler: information not available" otherwise.
OPENSSL_BUILT_ON
The date of the build process in the form "built on: ..." if available or "built on: date not available" otherwise.
OPENSSL_PLATFORM
The "Configure" target of the library build in the form "platform: ..." if available or "platform: information not available" otherwise.
OPENSSL_DIR
The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "..."" if available or "OPENSSLDIR: N/A" otherwise.
OPENSSL_ENGINES_DIR
The "ENGINESDIR" setting of the library build in the form "ENGINESDIR: "..."" if available or "ENGINESDIR: N/A" otherwise.
For an unknown t, the text "not available" is returned.

RETURN VALUE

The version number.
