# DPInstallWrapper2 Documentation
|
|
|
|
## 1. Purpose
|
|
|
|
This module serves as a shim wrapper for executing driver installer executables (specifically `dpinst.exe`) within the DataPRO installation process. Its primary purpose is to work around a known quirk where the wrapped executable returns non-zero exit codes even on successful installations. By always returning `0` to the calling installer, it prevents false failure conditions from propagating up the installation chain.
|
|
|
|
## 2. Public Interface
|
|
|
|
### `DPInstallWrapper2.Main`
|
|
|
|
**Signature:**
|
|
```csharp
|
|
static int Main(string[] args)
|
|
```
|
|
|
|
**Behavior:**
|
|
- Entry point for the wrapper executable.
|
|
- Expects `args[0]` to be the path to the executable to run.
|
|
- Passes exactly three arguments (`args[1]`, `args[2]`, `args[3]`) to the spawned process.
|
|
- Automatically quotes any argument containing a space character by wrapping it in double quotes.
|
|
- Launches the target process synchronously, waits for completion, and always returns `0` regardless of the child process's actual exit code.
|
|
|
|
## 3. Invariants
|
|
|
|
- **Argument count requirement:** The caller must supply at least 4 arguments. If fewer than 4 arguments are provided, the code will throw an `IndexOutOfRangeException` when accessing `lArgs[1]`, `lArgs[2]`, or `lArgs[3]`.
|
|
- **Fixed argument passing:** Exactly three arguments are forwarded to the child process. Any additional arguments beyond `args[3]` are silently ignored.
|
|
- **Return value:** The method always returns `0` (success), regardless of the wrapped process's actual exit code.
|
|
|
|
## 4. Dependencies
|
|
|
|
**This module depends on:**
|
|
- `System.Collections.Generic` — for `List<string>` used to manipulate arguments
|
|
- `System.Diagnostics` — for the `Process` class used to spawn and manage the child process
|
|
|
|
**Dependents:** Not determinable from source alone; this is a standalone executable invoked by the DataPRO installer infrastructure.
|
|
|
|
## 5. Gotchas
|
|
|
|
1. **Exit code is discarded:** The wrapper captures `proc.ExitCode` into a local variable `exitCode` but never uses it. All failures of the child process are masked and reported as success. This could hide genuine installation failures.
|
|
|
|
2. **Off-by-one in quoting logic:** The loop iterates from `i = 1` to `i < args.Length`, but `lArgs[0]` (the executable path) is never quoted. This may be intentional since `FileName` property typically doesn't require quoting |
