How Can I Efficiently Convert C Code to C?

Converting C Code to C: A Practical Approach

As developers often encounter the need to convert C code to C, it's essential to understand the complexities involved. While manual conversion is possible, it requires meticulous attention to C -specific constructs and semantics.

Automated Conversion Tools

Simplifying the conversion process, Comeau's C compiler emerges as a valuable tool. It generates C code that maintains its integrity through dynamic conversion from the original C code. This eliminates the need for manual upkeep of the C code, ensuring consistency and reducing maintenance efforts.

Manual Conversion Considerations

Despite the availability of automated tools, there may be instances where manual conversion is warranted. Here are key considerations for such conversions:

• Class Conversion: C classes should be converted to C structures, retaining the data members.
• Member Functions: Member functions need to be converted into function pointers stored within the newly defined structures.
• Constructors and Destructors: Constructors and destructors do not exist in C. Their functionality can be incorporated into separate init() and deinit() functions.
• Templates: Templates, a fundamental element of C , have no direct equivalent in C. Consider expanding the template-generated code into multiple source files.
• Namespaces: Namespaced declarations in C should be addressed by using C equivalent macros like extern.
