Attempts to read `n` bytes starting at the current file offset from the open file referred to by `f`. Bytes read are stored in the memory buffer at address `b` which must be at least `n` bytes in size. The function advances the file offset by the amount read, and returns the number of bytes actually read, which may be less than `n`. If `f` does not refer to an open file, the function will set `ec` to `errc::invalid_argument` and return immediately. The function will ensure that `!ec` is `true` if there was no error or set to the appropriate error code if an error occurred. If an end-of-file condition is detected prior to reading any bytes, the function will ensure that `!ec` is `true` and the return value shall be 0.

This representation addresses a narrow range of use cases. It has limited potential for customization and performance. It is more difficult to use because it excludes the start line fields from the model.

In both of these cases, an object with a specific type is used in place of the completion handler, and the return value of the initiating function is transformed from `void` to `std::future<std::size_t>` or `std::size_t`. The handler is sometimes called a __CompletionToken__ when used in this context. The return type transformation is supported by customization points in the initiating function signature. Here is the signature for [@boost:/doc/html/boost_asio/reference/async_write/overload1.html `net::async_write`]:

Adjusts the [@https://tools.ietf.org/html/rfc7230#section-3.3.1 [*Transfer-Encoding]] field value as follows:

[itemized_list [ If `b` is `true`, the "chunked" token is appended to the list of encodings if it does not already appear last in the list. If the Transfer-Encoding field is absent, the field will be inserted to the container with the value "chunked". ][ If `b` is `false, the "chunked" token is removed from the list of encodings if it appears last in the list. If the result of the removal leaves the list of encodings empty, the Transfer-Encoding field shall not appear when the associated __FieldsWriter__ serializes the fields. ]]

If the result of adjusting the field value produces an empty string, the field is removed from the container.

Set a callback to be invoked on chunk body data.

The callback will be invoked one or more times to provide buffers corresponding to the chunk body for the current chunk. The callback receives the number of octets remaining in this chunk body including the octets in the buffer provided.

The callback must return the number of octets actually consumed. Any octets not consumed will be presented again in a subsequent invocation of the callback. The implementation type-erases the callback without requiring a dynamic allocation. For this reason, the callback object is passed by a non-constant reference.

The function object will be called with this equivalent signature:
