OS	Architectures	Shared Library Format	Status	Loader Notes
Windows	`386`, `amd64`, `arm64`	PE (`.dll`)	Supported	In-memory PE loader
Darwin	`amd64`, `arm64`	Mach-O (`.dylib`, bundle)	Supported	Dyld4 root-image loader with system dependencies registered through public dyld; supports no-cgo builds and avoids temp-file legacy NS APIs.
Linux	`386`, `amd64`, `arm64`	ELF (`.so`)	Supported	Pure Go in-memory ELF loader (maps PT_LOAD segments, applies relocations, resolves externals from runtime modules/`dlsym`); no `memfd`, no `/dev/shm`, no temp-file disk writes.
Other	-	-	Unsupported	Returns an explicit unsupported-platform error.

Public API

Import path:

import "github.com/sliverarmory/reflektor"

Example:

payload := []byte{}

lib, err := reflektor.LoadLibrary(payload)
if err != nil {
    return err
}
defer lib.Close()

if err := lib.CallExport("StartW"); err != nil {
    return err
}

You can also load from a path:

lib, err := reflektor.LoadLibraryFile("./payload.dylib")

CLI

The CLI is in reflektor/cli and uses Cobra.

Build:

go build -o reflektor ./cli

Usage:

./reflektor <shared-library-path> [--call-export StartW]

--call-export defaults to StartW.

Behavior Notes

CallExport is designed for zero-argument exports.
Reflektor normalizes common symbol naming differences where possible (for example underscore-prefixed forms).
The root reflektor.Library interface is intentionally small: CallExport() and Close().

Test Data And Validation

C test shared libraries are generated from:

reflektor/testdata/c/basic.c

The Rust HTTPS fixture is built from reflektor/testdata/rust. It exports StartW, performs a bounded GET https://example.com/ through libcurl on Darwin/Linux or WinHTTP on Windows, and records ok:200 after receiving a non-empty successful response. The fixture is dependency-free Rust (no_std) so it does not require unsupported thread-local runtime state from the in-memory loaders.

Build test shared libraries for the full matrix:

./testdata/build_c_shared_libs.sh

Run tests:

go test ./...

The Rust fixture test requires Cargo with Rust 1.94.0 and outbound HTTPS access. Linux also requires the libcurl development package so the fixture can link against the system TLS client.
