Classes

c
Deno.UnsafeCallback

An unsafe function pointer for passing JavaScript functions as C function pointers to foreign function calls.

c
Deno.UnsafeFnPointer

An unsafe pointer to a function, for calling functions that are not present as symbols.

c
Deno.UnsafePointer

A collection of static functions for interacting with pointer objects.

c
Deno.UnsafePointerView

An unsafe pointer view to a memory location as specified by the pointer value. The UnsafePointerView API follows the standard built in interface DataView for accessing the underlying types at an memory location (numbers, strings and raw bytes).

Functions

f
Deno.dlopen

Opens an external dynamic library and registers symbols, making foreign functions available to be called.

Interfaces

I
Deno.DynamicLibrary

A dynamic library resource. Use Deno.dlopen to load a dynamic library and return this interface.

I
Deno.ForeignFunction

The interface for a foreign function as defined by its parameter and result types.

I
Deno.ForeignLibraryInterface

A foreign library interface descriptor.

I
Deno.ForeignStatic
No documentation available
I
Deno.NativeStructType

The native struct type for interfacing with foreign functions.

I
Deno.PointerObject

A non-null pointer, represented as an object at runtime. The object's prototype is null and cannot be changed. The object cannot be assigned to either and is thus entirely read-only.

I
Deno.UnsafeCallbackDefinition

Definition of a unsafe callback function.
