Classes

c
Deno.UnsafeCallback

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

c
Deno.UnsafeFnPointer

An unsafe pointer to a function, for calling functions that are not presentas 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 pointervalue. The UnsafePointerView API follows the standard built in interfaceDataView for accessing the underlying types at an memorylocation (numbers, strings and raw bytes).

Functions

f
Deno.dlopen

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

Interfaces

I
Deno.DynamicLibrary

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

I
Deno.ForeignFunction

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

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 objectat runtime. The object's prototype is nulland cannot be changed. The object cannot beassigned to either and is thus entirely read-only.

I
Deno.UnsafeCallbackDefinition

Definition of a unsafe callback function.
