Declarations of entities to handle VPI versioning.
These utilities allow querying the VPI header and library versions and properly handle VPI forward- or backward-compatibility .
| #define NV_VPI_MAKE_VERSION | ( | MAJOR, | |
| MINOR, | |||
| PATCH | |||
| ) | ((MAJOR)*1000000 + (MINOR)*10000 + (PATCH)*100) |
#include <vpi/Version.h>
Assemble an integer version from its components.
This makes it easy to conditionally compile code for different VPI versions, e.g:
| #define NV_VPI_VERSION 40400 |
#include <vpi/Version.h>
VPI library version.
It's an integer value computed from MAJOR*1000000 + MINOR*10000 + PATCH*100 + TWEAK. Integer versions can be compared, recent versions are greater than older ones.
| #define NV_VPI_VERSION_MAJOR 0 |
#include <vpi/Version.h>
Major version number component.
This is incremented every time there's a incompatible ABI change. In the special case of major version 0, compatibility between minor versions is not guaranteed.
| #define NV_VPI_VERSION_MINOR 4 |
#include <vpi/Version.h>
Minor version number component.
This is incremented every time there's a new feature added to VPI that doesn't break backward compatibility. This number is reset to zero when major version changes.
| #define NV_VPI_VERSION_PATCH 4 |
#include <vpi/Version.h>
Patch version number component.
This is incremented every time a bug is fixed, but no new functionality is added to the library. This number is reset to zero when minor version changes.
| #define NV_VPI_VERSION_SUFFIX |
#include <vpi/Version.h>
Version suffix.
String appended to version number to designate special builds.
| #define NV_VPI_VERSION_TWEAK 0 |
#include <vpi/Version.h>
Tweak version number component.
Incremented for packaging or documentation updates, etc. The library itself isn't updated. Gets reset to zero when patch version changes.
| int vpiGetVersion | ( | void | ) |
#include <vpi/Version.h>
Retrieves the library's version number.
The number is represented as a integer. It may differ from NV_VPI_VERSION if header doesn't correspond to VPI binary. This can be used by user's program to handle semantic differences between library versions.
