Macro Definition Documentation

#define OPENVDB_API   OPENVDB_IMPORT

Helper macros for defining library symbol visibility.

All classes and public free standing functions must be explicitly marked as <lib>_API to be exported. The <lib>_PRIVATE macros are defined when building that particular library.

#define OPENVDB_CHECK_GCC (   MAJOR,
  MINOR 
)    0

Macro for determining if GCC version is >= than X.Y.

#define OPENVDB_DEPRECATED   __attribute__ ((deprecated))

Use OPENVDB_DEPRECATED to mark functions as deprecated. It should be placed right before the signature of the function, e.g., "OPENVDB_DEPRECATED void functionName();".

#define OPENVDB_HOUDINI_API   OPENVDB_IMPORT
#define OPENVDB_NO_UNREACHABLE_CODE_WARNING_BEGIN

Bracket code with OPENVDB_NO_UNREACHABLE_CODE_WARNING_BEGIN/_END, as in the following example, to inhibit ICC remarks about unreachable code:

1 template<typename NodeType>
2 void processNode(NodeType& node)
3 {
4  OPENVDB_NO_UNREACHABLE_CODE_WARNING_BEGIN
5  if (NodeType::LEVEL == 0) return; // ignore leaf nodes
6  int i = 0;
7  ...
8  OPENVDB_NO_UNREACHABLE_CODE_WARNING_END
9 }

In the above, NodeType::LEVEL == 0 is a compile-time constant expression, so for some template instantiations, the line below it is unreachable.

#define OPENVDB_NO_UNREACHABLE_CODE_WARNING_END
#define OPENVDB_STATIC_SPECIALIZATION   static

Macro for determining if there are sufficient C++0x/C++11 features.

For compilers that need templated function specializations to have storage qualifiers, we need to declare the specializations as static inline. Otherwise, we'll get linker errors about multiply defined symbols.
