GObject introspection is a middleware layer between C
|
libraries (using GObject) and language bindings. The C library
|
can be scanned at compile time and generate a metadata file,
|
in addition to the actual native C library. Then at runtime,
|
language bindings can read this metadata and automatically
|
provide bindings to call into the C library.
