## Define Documentation

#define ANGELSCRIPT_VERSION 21902

Version 2.19.2

## Typedef Documentation

typedef void(* asJITFunction)(asSVMRegisters *registers, asDWORD entryId)

Parameters:

  `[in]` | registers | A pointer to the virtual machine's registers.
  `[in]` | entryId | The value defined by the JIT compiler for the current entry point in the JIT function.

A JIT function receives a pointer to the virtual machine's registers when called and an argument telling it where in the script function to continue the execution. The JIT function must make sure to update the VM's registers according to the actions performed before returning control to the VM.

## Function Documentation

AS_API asIScriptEngine* asCreateScriptEngine | ( | asDWORD | version | ) |

Parameters:

  `[in]` | version | The library version. Should always be ANGELSCRIPT_VERSION.

Returns:
  A pointer to the script engine interface.

Call this function to create a new script engine. When you're done with the script engine, i.e. after you've executed all your scripts, you should call Release on the pointer to free the engine object.

AS_API asIScriptContext* asGetActiveContext | ( |  | ) |

Returns:
  A pointer to the currently executing context, or null if no context is executing.

This function is most useful for registered functions, as it will allow them to obtain a pointer to the context that is calling the function, and through that get the engine, or custom user data.

If the script library is compiled with multithread support, this function will return the context that is currently active in the thread that is being executed. It will thus work even if there are multiple threads executing scripts at the same time.

This function does not increase the reference count of the context.

AS_API const char* asGetLibraryOptions | ( |  | ) |

Returns:
  A null terminated string with indicators that identify the options used to compile the script library.

This can be used to identify at run-time different ways to configure the engine. For example, if the returned string contain the identifier AS_MAX_PORTABILITY then functions and methods must be registered with the asCALL_GENERIC calling convention.

AS_API const char* asGetLibraryVersion | ( |  | ) |

Returns:
  A null terminated string with the library version.

The returned string can be used for presenting the library version in a log file, or in the GUI.

AS_API int asResetGlobalMemoryFunctions | ( |  | ) |

Returns:
  A negative value on error.

Call this method to restore the default memory management functions.

AS_API int asSetGlobalMemoryFunctions | ( | asALLOCFUNC_t | allocFunc,
|  | asFREEFUNC_t | freeFunc |
| ) |  |  |

Parameters:

  `[in]` | allocFunc | The function that will be used to allocate memory.
  `[in]` | freeFunc | The function that will be used to free the memory.

Returns:
  A negative value on error.

Call this method to register the global memory allocation and deallocation functions that AngelScript should use for memory management. This function Should be called before asCreateScriptEngine.

If not called, AngelScript will use the malloc and free functions from the standard C library.

AS_API int asThreadCleanup | ( |  | ) |

Returns:
  A negative value on error.

Return values:

  | asCONTEXT_ACTIVE | A context is still active.

Call this method before terminating a thread that has accessed the engine to clean up memory allocated for that thread.

It's not necessary to call this if only a single thread accesses the engine.
