Driver Dev Tutor-Cross-Platform Driver Coding

Example

Guidance on organizing a project repository with folders for shared and platform-specific code, e.g., separate directories for Windows-specific and Linux-specific driver implementations alongside a common directory for shared utilities like logging and error handling.

Scenario

A developer needs to create a file system driver that should operate both on Windows and Linux. Driver Dev Tutor helps in setting up the project structure to maximize code reusability and simplify maintenance.

Example

Instruction on designing an abstraction interface to wrap OS-specific APIs that handle device communication, ensuring that the main driver logic can call these interfaces without depending on direct system calls.

Scenario

Developing a network card driver that uses different APIs to send and receive data on Windows and Linux. Driver Dev Tutor assists in creating an abstraction layer that the main driver code uses, regardless of the underlying OS.

Example

Examples of using preprocessor directives to include or exclude code segments based on the target OS, such as #ifdef _WIN32 for Windows-specific code blocks.

Scenario

When a piece of code within a multimedia driver must interact differently with hardware depending on whether it's compiled for macOS or Linux. Driver Dev Tutor demonstrates how to use conditional compilation to ensure correct functionality on both platforms without duplication.
