Member Typedef Documentation

◆ ReadCallback

using ACurl::ReadCallback = std::function<std::size_t(char* dst, size_t maxLen)>

A read callback.

Parameters

dst	destination buffer you should write to.
maxLen	destination buffer size aka max length.

Returns: bytes written to the destination buffer. Zero means data unavailability (but the stream may be continued in the future).

Unlike regular streams, blocking is not allowed. To indicate the data unavailability, return zero. To indicate end of file, throw an AEOFException.

◆ WriteCallback

using ACurl::WriteCallback = std::function<size_t(AByteBufferView data)>

A read callback.

Parameters

data	received data

Returns: bytes written to the destination buffer. Zero means buffer does not have enough space to store supplied data (but the stream may be continued in the future), the supplied data is not discarded and being kept in the curl buffers.

Unlike regular streams, blocking is not allowed. To indicate buffer overflow, return zero. To indicate end of file, throw an AEOFException.

Member Function Documentation

◆ close()

void ACurl::close ( )

virtual

Breaks curl loop in the run() method, closing underlying curl connection.

curl does not have a function which immediately stops the transfer (see https://curl.se/docs/faq.html#How_do_I_stop_an_ongoing_transfe). The stop functionality is handled in ACurl by returning error code on all callbacks. close() function is non-blocking, and some time would be taken until the run() method finally returns.

After calling close() method, none of the result signals (like fail, success) will be called.

close() is non-blocking function.

close() is thread-safe.

Reimplemented in AWebsocket.

Member Data Documentation

◆ fail

emits<ErrorDescription> ACurl::fail

Emitted on network error.

Note: A protocol-level error (like HTTP(S) 404) is not treated as a fail. Check for response code via the getResponseCode() function.

◆ success

emits ACurl::success

Emitted on success.

Note: A protocol-level error (like HTTP(S) 404) is not treated as a fail. Check for response code via the getResponseCode() function.
