Set transfer options

All callback functions shouldn't raise exceptions. Any exception raised in callback function will be silently caught and discarded, and the transfer will be aborted.

Sourceval set_writefunction : t -> (string -> int) -> unit

Sourceval set_writefunction2 : t -> (string -> write_result) -> unit

Sourceval set_writefunction_buf : t -> (bigstring -> write_result) -> unit

A write callback that provides direct access to curl's receive buffer. The provided buffer may only be read within the callback. It is illegal for the buffer to escape the scope of the callback.

This function provides better performance than string-based variants by avoiding an intermediate copy.

Sourceval set_readfunction : t -> (int -> string) -> unit
