This graph shows which files directly or indirectly include this file:
Namespaces | |
namespace | Exiv2 |
Defines | |
#define | EXIV2_MAJOR_VERSION (0) |
Exiv2 MAJOR version number of the library used at compile-time. | |
#define | EXIV2_MINOR_VERSION (14) |
Exiv2 MINOR version number of the library used at compile-time. | |
#define | EXIV2_PATCH_VERSION (0) |
Exiv2 PATCH version number of the library used at compile-time. | |
#define | EXIV2_MAKE_VERSION(major, minor, patch) (((major) << 16) | ((minor) << 8) | (patch)) |
Make an integer version number for comparison from a major, minor and a patch version number. | |
#define | EXIV2_VERSION EXIV2_MAKE_VERSION(EXIV2_MAJOR_VERSION,EXIV2_MINOR_VERSION,EXIV2_PATCH_VERSION) |
The Exiv2 version number of the library used at compile-time as an integer number for easy comparison. | |
#define | EXIV2_CHECK_VERSION(major, minor, patch) ( Exiv2::versionNumber() >= EXIV2_MAKE_VERSION(major,minor,patch) ) |
Check the version of the available Exiv2 library at runtime. Return true if it is the same as or newer than the passed-in version. | |
Functions | |
int | Exiv2::versionNumber () |
Return the version of Exiv2 available at runtime as an integer. | |
const char * | Exiv2::version () |
Return the version of Exiv2 available at runtime as a string. |
#define EXIV2_CHECK_VERSION | ( | major, | |||
minor, | |||||
patch | ) | ( Exiv2::versionNumber() >= EXIV2_MAKE_VERSION(major,minor,patch) ) |
Check the version of the available Exiv2 library at runtime. Return true if it is the same as or newer than the passed-in version.
Versions are denoted using a standard triplet of integers: MAJOR.MINOR.PATCH. The basic intent is that MAJOR versions are incompatible, large-scale upgrades of the API. MINOR versions retain source and binary compatibility with older minor versions, and changes in the PATCH level are perfectly compatible, forwards and backwards.
Details of these guidelines are described in http://apr.apache.org/versioning.html
It is important to note that as long as the library has not reached 1.0.0 it is not subject to the guidelines described in the document above. Before a 1.0 release (version 0.x.y), the API can and will be changing freely, without regard to the restrictions detailed in the above document.
