1=pod 2 3=head1 NAME 4 5OPENSSL_VERSION_NUMBER, OPENSSL_VERSION_TEXT, OpenSSL_version, 6OpenSSL_version_num - get OpenSSL version number 7 8=head1 SYNOPSIS 9 10 #include <openssl/opensslv.h> 11 #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL 12 #define OPENSSL_VERSION_TEXT "OpenSSL x.y.z xx XXX xxxx" 13 14 #include <openssl/crypto.h> 15 16 unsigned long OpenSSL_version_num(); 17 const char *OpenSSL_version(int t); 18 19=head1 DESCRIPTION 20 21OPENSSL_VERSION_NUMBER is a numeric release version identifier: 22 23 MNNFFPPS: major minor fix patch status 24 25The status nibble has one of the values 0 for development, 1 to e for betas 261 to 14, and f for release. 27 28for example 29 30 0x000906000 == 0.9.6 dev 31 0x000906023 == 0.9.6b beta 3 32 0x00090605f == 0.9.6e release 33 34Versions prior to 0.9.3 have identifiers E<lt> 0x0930. 35Versions between 0.9.3 and 0.9.5 had a version identifier with this 36interpretation: 37 38 MMNNFFRBB major minor fix final beta/patch 39 40for example 41 42 0x000904100 == 0.9.4 release 43 0x000905000 == 0.9.5 dev 44 45Version 0.9.5a had an interim interpretation that is like the current one, 46except the patch level got the highest bit set, to keep continuity. The 47number was therefore 0x0090581f. 48 49OPENSSL_VERSION_TEXT is the text variant of the version number and the 50release date. For example, 51"OpenSSL 1.0.1a 15 Oct 2015". 52 53OpenSSL_version_num() returns the version number. 54 55OpenSSL_version() returns different strings depending on B<t>: 56 57=over 4 58 59=item OPENSSL_VERSION 60 61The text variant of the version number and the release date.
