Public C API declarations for diagnostics.

Function Documentation

mln_thread_last_error_message()

const char * mln_thread_last_error_message

(

void

)

Returns the last thread-local diagnostic message.

The returned string is empty when no diagnostic is available. The pointer is owned by the C API and remains valid until the next C API call on the same thread that writes a thread-local diagnostic.

mln_thread_token()

uint64_t mln_thread_token

(

void

)

Returns an opaque token identifying the calling native thread.

The token is stable for the life of the thread and differs between live threads. It carries no meaning beyond comparison, and a token from a thread that has exited may be reused by a later one.

Owner-thread checks in this API key on the native thread. A host whose unit of execution is not pinned to one, such as a Dart isolate or an unlocked goroutine, compares this token across calls to detect that it moved.

Callable from any thread.
