Plugin namespace helpers

To avoid symbol conflicts when employing static linking, it is a good idea to put everything into a private namespace.

The CS_PLUGIN_NAMESPACE_BEGIN and CS_PLUGIN_NAMESPACE_END macros help with that by putting the plugin namespace into a sub-namespace for plugins.

Use like:

 #include <...>

 CS_IMPLEMENT_PLUGIN

 CS_PLUGIN_NAMESPACE_BEGIN(MyPlugin)
 {
   ...
   MyClass::MyClass (...) { ... }
   ...
 }
 CS_PLUGIN_NAMESPACE_END(MyPlugin)

To refer to members of the namespace (e.g. for template specializations, use CS_PLUGIN_NAMESPACE_NAME.



#define CS_PLUGIN_NAMESPACE_BEGIN(name)   namespace CS_NAMESPACE_PACKAGE_NAME { namespace Plugin { namespace name
#define CS_PLUGIN_NAMESPACE_END(name)   } }
#define CS_PLUGIN_NAMESPACE_NAME(name)   CS_NAMESPACE_PACKAGE_NAME::Plugin::name

Functions

static void CS::Debug::DebugBreak ()
 Break execution for debugging purposes.
void CS::Debug::DumpAllocateMemoryBlocks ()
 Print all memory blocks allocated with the "checking" functions, including where they were allocated, to a file "allocations.txt".
bool CS::Debug::VerifyAllMemory ()
 Verify that all memory blocks allocated with the "checking" functions did not overrun or the allocated space.

Detailed Description

This file should be #included before any other Crystal Space header files.

It sets up a compilation environment which smooths over differences between platforms, allowing the same code to compile cleanly over a variety of operating systems and build tools. It also provides a number of utility macros useful to projects utilizing Crystal Space and to the Crystal Space code itself.

Definition at line 270 of file cssysdef.h.

#define CS_DEPRECATION_WARNINGS_DISABLE

Disable deprecation warnings in following statements.

Always try to actually fix the root cause of a deprecation warning before employing this. Should be followed by CS_DEPRECATION_WARNINGS_ENABLE after the statements that caused the warnings. Suitable for use in macros.

Definition at line 1270 of file cssysdef.h.

#define CS_DEPRECATION_WARNINGS_ENABLE

Enable deprecation warnings in following statements.

Suitable for use in macros.

Definition at line 1271 of file cssysdef.h.

#define CS_FUNCTION_NAME   __PRETTY_FUNCTION__

Macro that resolves to a compiler-specific variable or string that contains the name of the current function.

Definition at line 782 of file cssysdef.h.

#define CS_HEADER_GLOBAL ( X,
 )     CS_HEADER_GLOBAL_COMPOSE(X,Y)

The CS_HEADER_GLOBAL() macro composes a pathname from two components and wraps the path in `<' and `>'.

This macro is useful in cases where one does not have the option of augmenting the preprocessor's header search path, even though the include path for some header file may vary from platform to platform. For instance, on many platforms OpenGL headers are in a `GL' directory, whereas on other platforms they are in an `OpenGL' directory. As an example, in the first case, the platform might define the preprocessor macro GLPATH with the value `GL', and in the second case GLPATH would be given the value `OpenGL'. To actually include an OpenGL header, such as gl.h, the following code would be used:

 #include CS_HEADER_GLOBAL(GLPATH,gl.h)
 

Definition at line 339 of file cssysdef.h.

#define CS_HEADER_LOCAL ( X,
 )     CS_HEADER_LOCAL_COMPOSE1(X,Y)

The CS_HEADER_LOCAL() macro composes a pathname from two components and wraps the path in double-quotes.

This macro is useful in cases where one does not have the option of augmenting the preprocessor's header search path, even though the include path for some header file may vary from platform to platform. For example, assuming that the preprocessor macro UTILPATH is defined with some platform-specific value, to actually include a header, such as util.h, the following code would be used:

 #include CS_HEADER_LOCAL(UTILPATH,util.h)
 

Definition at line 354 of file cssysdef.h.

#define CS_IMPLEMENT_APPLICATION
Value:
CS_DECLARE_DEFAULT_STATIC_VARIABLE_REGISTRATION                 \
  CS_DEFINE_STATIC_VARIABLE_REGISTRATION (csStaticVarCleanup_csutil);   \
  CS_IMPLEMENT_PLATFORM_APPLICATION                                     \
  CS_DEFINE_MEMTRACKER_MODULE

The CS_IMPLEMENT_APPLICATION macro should be placed at the global scope in exactly one compilation unit comprising an application.

For maximum portability, each application should employ this macro. Platforms may override the definition of this macro in order to augment the implementation of an application with any special implementation details required by the platform.

Definition at line 566 of file cssysdef.h.

#define CS_IMPLEMENT_FOREIGN_DLL
Value:
CS_IMPLEMENT_STATIC_VARIABLE_REGISTRATION(csStaticVarCleanup_local); \
       CS_DEFINE_STATIC_VARIABLE_REGISTRATION (csStaticVarCleanup_local);   \
       CS_DEFINE_MEMTRACKER_MODULE

The CS_IMPLEMENT_FOREIGN_DLL macro should be placed at the global scope in exactly one compilation unit comprising a foreign (non-Crystal Space) module.

For maximum portability, each such module should employ this macro. This is useful for situations in which a dynamic load library (DLL) is being built for some other facility. Obvious examples are pure extension modules for Python, Perl, and Java. For Crystal Space plugins, instead use CS_IMPLEMENT_PLUGIN. Platforms may override the definition of this macro in order to augment the implementation of the foreign module with any special implementation details required by the platform. If the foreign module will be interacting with Crystal Space, then it also needs to initialize the global iSCF::SCF variable manually. This variable should be set to point at the single shared instance of iSCF which is created by the application's invocation of scfInitialize(), csInitializer::InitializeSCF(), or csInitializer::CreateEnvironment(). In real Crystal Space plugins (those using CS_IMPLEMENT_PLUGIN), iSCF::SCF is initialized automatically; but in foreign DLL's, it is the responsibility of the DLL's author to ensure that iSCF::SCF gets initialized.

Definition at line 508 of file cssysdef.h.

#define CS_IMPLEMENT_IMPLICIT_PTR_CAST ( classname   ) 
Value:
inline static classname* _CS_IMPLICITPTRCAST_NAME (classname* ptr) \
  { \
    return ptr;\
  }

Implements a static member function for a class which can be used to perform implicit pointer casts.

Parameters:
classname Name of the class that the macro is being used in.
Remarks:
This macro is intended to support typecasting within macros, allowing the compiler to provide a more descriptive error message. Use CS_IMPLEMENT_IMPLICIT_PTR_CAST() in the declaration of the class and CS_IMPLICIT_PTR_CAST() in the macro declaration.
Example:
 struct iObjectRegistry : public iBase
 {
   // Allow implicit casts through static function.
   CS_IMPLEMENT_IMPLICIT_PTR_CAST(iObjectRegistry);
   ...
 }

 #define CS_QUERY_REGISTRY_TAG(Reg, Tag) \
  csPtr<iBase> (CS_IMPLICIT_PTR_CAST(iObjectRegistry, Reg)->Get (Tag))

Definition at line 1176 of file cssysdef.h.

#define CS_IMPLEMENT_PLUGIN
Value:
CS_IMPLEMENT_STATIC_VARIABLE_REGISTRATION(csStaticVarCleanup_local)     \
   CS_DEFINE_STATIC_VARIABLE_REGISTRATION (csStaticVarCleanup_local);   \
   CS_IMPLEMENT_PLATFORM_PLUGIN                                         \
   CS_DEFINE_MEMTRACKER_MODULE

The CS_IMPLEMENT_PLUGIN macro should be placed at the global scope in exactly one compilation unit comprising a plugin module.

For maximum portability, each plugin module must employ this macro. Platforms may override the definition of this macro in order to augment the implementation of the plugin module with any special implementation details required by the platform.

Definition at line 548 of file cssysdef.h.

#define CS_IMPLEMENT_STATIC_CLASSVAR ( Class,
var,
getterFunc,
Type,
initParam   )     CS_IMPLEMENT_STATIC_CLASSVAR_EXT(Class,var,getterFunc,Type,initParam,0,_kill)

Create the static class variable that has been declared with CS_DECLARE_STATIC_CLASSVAR.

This will also create the Getter function and the destruction function. The destruction function will be registered upon the first invocation of the Getter function. Example:

 CS_IMPLEMENT_STATIC_CLASSVAR (csPolygon2D, pool, GetVertexPool,
                               csVertexPool,)
 

Definition at line 730 of file cssysdef.h.

#define CS_IMPLEMENT_STATIC_VAR ( getterFunc,
Type,
initParam   )     CS_IMPLEMENT_STATIC_VAR_EXT(getterFunc,Type,initParam,0,_kill)

Implement a file-scoped static variable that is created on demand.

Defines a 'getter' function to access the variable and a 'destruction' function. The 'getter' function will register the 'destruction' function on first invocation. Example:

 CS_IMPLEMENT_STATIC_VAR (GetVertexPool, csVertexPool,)
 

This will give you a file-scoped static 'getter' function GetVertexPool() that returns a pointer to a static variable.

Definition at line 664 of file cssysdef.h.

#define CS_IMPLICIT_PTR_CAST ( classname,
ptr   )     (classname::_CS_IMPLICITPTRCAST_NAME(ptr))

Perform a compiler implicit cast of a pointer to another pointer type using a static member function declared with the CS_IMPLEMENT_IMPLICIT_PTR_CAST macro.

Parameters:
classname Name of the class to convert to
ptr Pointer to be convereted into
See also:
CS_IMPLEMENT_IMPLICIT_PTR_CAST

Definition at line 1190 of file cssysdef.h.

#define CS_INITIALIZE_PLATFORM_APPLICATION

Perform platform-specific application initializations.

This macro should be invoked very near to the "beginning" of the application.

Remarks:
NB: It is invoked in csInitializer::CreateEnvironment().

Definition at line 402 of file cssysdef.h.

#define CS_NO_EXCEPTIONS

This is defined when the project was compiled without support for exceptions.

Definition at line 284 of file cssysdef.h.

#define CS_REGISTER_STATIC_FOR_DESTRUCTION ( getterFunc   )     csStaticVarCleanup (getterFunc);

Register a method that will destruct one static variable.

Definition at line 577 of file cssysdef.h.

#define CS_STATIC_VARIABLE_CLEANUP   csStaticVarCleanup (0);

Invoke the function that will call all destruction functions.

Definition at line 585 of file cssysdef.h.

#define CS_STRING_TO_WIDE (  )     CS_STRING_TO_WIDE_(x)

 void bar (const wchar_t* baz);
 #define FOO(x) bar (CS_STRING_TO_WIDE (#x));

Definition at line 1214 of file cssysdef.h.

#define CS_VA_COPY ( dest,
src   )     __va_copy(dest, src)
