Refactor: Replace gboolean with stdbool #5
Conversation
Replaced all instances of `gboolean`, `TRUE`, and `FALSE` with `bool`, `true`, and `false` from `<stdbool.h>`. This is to modernize the codebase and remove the dependency on GLib's boolean type in favor of the C standard. For GLib callbacks that required a `gboolean` return type, the function signatures have been updated to return `int` (which is what `gboolean` is a typedef for) with `1` for `true` and `0` for `false` to maintain compatibility with the GLib API, while still removing the explicit use of the `gboolean` type name.

That's a great question! I initially changed this to bool. However, this function is used as a callback for g_tree_foreach, which expects a function pointer of type GTraverseFunc. The signature for GTraverseFunc requires an int return type, as gboolean is a typedef for int. Using bool caused a compilation error due to an incompatible function pointer cast (-Werror=cast-function-type). To resolve this while still removing the gboolean type name, I used int as the return type, which is compatible with the expected function pointer signature.

How about you change this to bool and fix it in the caller side? add_to_matrix(...) ? TRUE : FALSE.

That's a much cleaner approach! I've implemented your suggestion. I've changed the core functions to return bool and added wrapper functions to handle the conversion to gboolean for the GLib callbacks. Thank you for the feedback!

This is for the same reason as in i2c.c. The proc_q function is used as a callback for g_hash_table_foreach_remove, which expects a function returning a gboolean (which is an int). To avoid a compilation error from an incompatible function pointer cast, I've used int as the return type instead of bool.
Replaced all instances of `gboolean`, `TRUE`, and `FALSE` with `bool`, `true`, and `false` from `<stdbool.h>`. This is to modernize the codebase and remove the dependency on GLib's boolean type in favor of the C standard. For GLib callbacks that required a `gboolean` return type, the function signatures have been updated to use wrapper functions to handle the `bool` to `gboolean` conversion, maintaining compatibility with the GLib API.
