Detailed Description

Cookbook Chapter 7: Dynamic Struct Marshalling.

This example demonstrates a powerful use of the introspection API: dynamically packing data from an arbitrary source into a C-compatible struct layout at runtime. This is a core task for any language binding or data serialization layer.

The infix_type_from_signature function is used to parse a signature string into a detailed infix_type graph. This graph contains all the size, alignment, and member offset information needed to correctly write data into a C-compatible memory buffer.

marshal_ordered_data()

static void marshal_ordered_data ( void *  dest, const char *  sig, void **  src  )

static

A generic marshalling function that packs data into a struct.

Parameters

dest	A pointer to the destination C struct buffer.
sig	The infix signature of the destination struct.
src	An array of void* pointers, where each pointer points to the source data for the corresponding member, in order.
