Swfdec has a three-part version number scheme. In this scheme, we use even vs. odd numbers to distinguish fixed points in the software vs. in-progress development, (such as from git instead of a tar file, or as a "snapshot" tar file as opposed to a "release" tar file).
1 2 3 4 5 |
_____ Major. Always 1, until we invent a new scheme. / ___ Minor. Even/Odd = Release/Snapshot (tar files) or Branch/Head (git) | / _ Micro. Even/Odd = Tar-file/git | | / 1.0.0 |
Here are a few examples of versions that one might see.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
Releases -------- 1.0.0 - A major release 1.0.2 - A subsequent maintenance release 1.2.0 - Another major release Snapshots --------- 1.1.2 - A snapshot (working toward the 1.2.0 release) In-progress development (eg. from git) -------------------------------------- 1.0.1 - Development on a maintenance branch (toward 1.0.2 release) 1.1.1 - Development on head (toward 1.1.2 snapshot and 1.2.0 release) |
Swfdec provides the ability to examine the version at either
compile-time or run-time and in both a human-readable form as well as an
encoded form suitable for direct comparison. Swfdec also provides the macro
SWFDEC_VERSION_ENCODE()
to perform the encoding.

Compile-time ------------ SWFDEC_VERSION_STRING Human-readable SWFDEC_VERSION Encoded, suitable for comparison Run-time -------- swfdec_version_string() Human-readable swfdec_version() Encoded, suitable for comparison |
For example, checking that the Swfdec version is greater than or equal to 1.0.0 could be achieved at compile-time or run-time as follows:
1 2 3 4 5 6 |
#if CAIRO_VERSION >= CAIRO_VERSION_ENCODE(1, 0, 0) printf ("Compiling with suitable cairo version: %s\n", %CAIRO_VERSION_STRING); #endif if (cairo_version() >= CAIRO_VERSION_ENCODE(1, 0, 0)) printf ("Running with suitable cairo version: %s\n", cairo_version_string ()); |
#define SWFDEC_VERSION_MAJOR
The major component of the version of Swfdec available at compile-time.
#define SWFDEC_VERSION_MICRO
The micro component of the version of Swfdec available at compile-time.
#define SWFDEC_VERSION_MINOR
The minor component of the version of Swfdec available at compile-time.
#define SWFDEC_VERSION_ENCODE(major, minor, micro)
This macro encodes the given Swfdec version into an integer. The numbers
returned by SWFDEC_VERSION
and swfdec_version()
are encoded using this
macro. Two encoded version numbers can be compared as integers. The
encoding ensures that later versions compare greater than earlier versions.
guint
swfdec_version (void
);
Returns the version of the Swfdec library encoded in a single
integer as per SWFDEC_VERSION_ENCODE
. The encoding ensures that
later versions compare greater than earlier versions.
A run-time comparison to check that Swfdec's version is greater than or equal to version X.Y.Z could be performed as follows:
1 |
if (swfdec_version() >= CAIRO_VERSION_ENCODE(X,Y,Z)) {...} |

as well as the compile-time
equivalents SWFDEC_VERSION
and SWFDEC_VERSION_STRING
.
const char *
swfdec_version_string (void
);
Returns the version of the Swfdec library as a human-readable string of the form "X.Y.Z".

as well as the compile-time equivalents
SWFDEC_VERSION_STRING
and SWFDEC_VERSION
.
#define SWFDEC_VERSION
The version of Swfdec available at compile-time, encoded using
SWFDEC_VERSION_ENCODE()
