rtfw_fastpath_handler_t

typedef void(* rtfw_fastpath_handler_t) (void *user_data)

#include <include/rtfw/rtfw.h>

Service a client-owned source in the zero-latency fast path.

The framework calls this required callback on every rtfw_fastpath_run invocation, after processing any pending command. Execution must be bounded and must not use kernel APIs, log, allocate, block, or perform cache maintenance. The handler owns source-event acknowledgment and may call rtfw_event_push.
