Writing a D Wrapper for a C Library

Posted on

In porting to D a program I created for a research project, I wrote a D wrapper of a C library in an object-oriented manner. I want to share my experience with other programmers. This article provides some D tips and tricks for writers of D wrappers around C libraries. I initially started my research … Continue reading Writing a D Wrapper for a C Library

To that end, it provides ABI compatibility, allows access to the C standard library, and makes use of the same object file formats and system linkers that C and C++ compilers use. Most built-in D types, even structs, are directly compatible with their C counterparts and can be passed freely to C functions, provided the functions have been declared in D with the appropriate linkage attribute. In many cases, one can copy a chunk of C code, paste it into a D module, and compile it with minimal adjustment. Conversely, appropriately declared D functions can be called from C.
