pydllmanager 0.1.0

A DLL management utility for Python by AtomixCore.

PyDLLManager

PyDLLManager is a Python library designed to simplify the process of loading and interacting with DLL (Dynamic Link Library) files. It allows you to effortlessly load DLLs, call functions, and manage data types using the ctypes module in Python.

Features

• Load DLLs: Easily load DLL files into your Python program.
• Retrieve Functions: Access functions within the DLL with automatic handling of argument and return types.
• Thread Safety: Includes built-in thread safety using threading.Lock.
• Decorator Support: Use the DllImprt decorator to automatically load and call functions from DLLs.

Installation

To install PyDLLManager, simply run the following pip command:

pip install pydllmanager

Usage

Basic Usage Example

1. First, you need to initialize a DLLLoader object by providing the path to your DLL file.

from pydllmanager import DLLLoader, ctypes_type

dll_path = "path/to/your/dll/file.dll"
loader = DLLLoader(dll_path)

2. Then, you can load functions from the DLL using the get_function method:

add_func = loader.get_function('add', [ctypes_type(int), ctypes_type(int)], ctypes_type(int))
result = add_func(5, 3)
print(result)  # Expected output: 8 (depends on the DLL function)

Using the include Decorator

The DllImprt decorator allows you to decorate functions to automatically load them from a DLL.

from pydllmanager import LoaderLibrary

loader = LoaderLibrary("path/to/your/dll/file.dll")
loader.load()

@loader.include()
def add(a: int, b: int) -> int: ... # The function is loaded from the DLL automatically

result = add(5, 3)
print(result)  # Expected output: 8

Example Code

from pydllmanager import DLLLoader, ctypes_type, LoaderLibrary

# Using DLLLoader to load and call a function
loader = DLLLoader("path/to/your/dll/file.dll")
subtract_func = loader.get_function('subtract', [ctypes_type(int), ctypes_type(int)], ctypes_type(int))
result = subtract_func(10, 4)
print(result)  # Expected output: 6 (depends on the DLL function)

loader = LoaderLibrary("path/to/your/dll/file.dll")
loader.load()

# Using DllImprt decorator
@loader.include()
def multiply(a: int, b: int) -> int: ...

result = multiply(2, 3)
print(result)  # Expected output: 6

Exception Handling

PyDLLManager defines a custom exception DLLManagerError to handle any errors during DLL loading or function retrieval. You can use it as follows:

try:
    loader = DLLLoader("invalid/path/to/dll.dll")
except DLLManagerError as e:
    print(f"Error loading DLL: {e}")

Compatibility

• Supports both 32-bit and 64-bit architectures.
• Compatible with most platforms that support the ctypes module in Python.
