Typedef Documentation

apply_func

typedef method_ret(* apply_func) (object *, object *, int)

Typedefs for ob_methods.

Also used in ob_types.c for storing the pointers temporarily. As a convention, callbacks parameters should begin with "ob_methods *context, object *ob", and return method_ret unless it needs to return something else.

Definition at line 30 of file ob_methods.h.

describe_func

typedef void(* describe_func) (const object *, const object *, int use_media_tags, char *buf, size_t size)

Definition at line 32 of file ob_methods.h.

method_ret

typedef char method_ret

Define some standard return values for callbacks which don't need to return any other results.

Later this might be expanded into a more complex return value system if necessary

Definition at line 14 of file ob_methods.h.

move_on_func

typedef method_ret(* move_on_func) (object *, object *, object *)

Definition at line 33 of file ob_methods.h.

process_func

typedef method_ret(* process_func) (object *)

Definition at line 31 of file ob_methods.h.

trigger_func

typedef method_ret(* trigger_func) (object *, object *, int)
