memaccess 0.1.1

# `memaccess`

Python library for Windows giving live access to a program's memory.

## Usage

`memaccess` exposes one main class to use for memory inspection: `MemoryView`.
It will request all necessary data from Windows to be able to read memory of
another application. Just pass to the class the process-id of the application
you want to observe:

```python
from memaccess import MemoryView

view = MemoryView(5555)
# Read memory...
view.close()
```

It's safer to use the context-manager variant of `MemoryView`:

```python
from memaccess import MemoryView

with MemoryView(5555) as view:
pass # Read memory...
```

> **NOTE**
>
> Accessing another program's memory requires elevated privileges, otherwise
> instantiation of `MemoryView` will fail.

To read content, `memaccess` exposes the `read` function. It takes the number of
bytes to read and the address where to start reading.

```python
# Read 8 bytes of memory at address 0x01234560
view.read(8, 0x01234560)
```

For convenience, `MemoryView` exposes read methods that convert values in memory
to respective C/C++ types.

```python
view.read_int(0x01234560)
view.read_float(0x01234564)
# ... and many others.
```

Please inspect the `MemoryView` class for details on all of those functions.

## Exceptions

Some exceptions are raised due to internal Windows API errors and show an error
code.

```
>>> from memaccess import MemoryView
>>> MemoryView(5555)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
...
RuntimeError: Can't open process with pid 5555, error code 87
```
