OPENSSL_VERSION_NUMBER 3 2003-07-24 0.9.9-dev OpenSSL

NAME

OPENSSL_VERSION_NUMBER, SSLeay, SSLeay_version - get OpenSSL version number

LIBRARY

libcrypto, -lcrypto

SYNOPSIS


 #include 
 #define OPENSSL_VERSION_NUMBER 0xnnnnnnnnnL


 #include 
 long SSLeay(void);
 const char *SSLeay_version(int t);

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 < 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.

_S_S_L_e_a_y_(_) 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.

_S_S_L_e_a_y___v_e_r_s_i_o_n_(_) returns different strings depending on tt:

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 compiler flags set for the compilation process in the form
"compiler: ..." if available or "compiler: information not available" otherwise.
SSLEAY_BUILT_ON The date of the build process in the form "built on: ..." if available
or "built on: date not available" otherwise.
SSLEAY_PLATFORM The "Configure" target of the library build in the form "platform: ..."
if available or "platform: information not available" otherwise.
SSLEAY_DIR The "OPENSSLDIR" setting of the library build in the form "OPENSSLDIR: "...""
if available or "OPENSSLDIR: N/A" otherwise.

For an unknown tt, the text "not available" is returned.

RETURN VALUE

The version number.
