Member Function Documentation

◆ read()

size_t nix::curlFileTransfer::TransferSource::read	(	char *	data,
		size_t	len )

inlineoverridevirtual

Store up to ‘len’ in the buffer pointed to by ‘data’, and return the number of bytes stored. It blocks until at least one byte is available.

Should not return 0 (generally you want to throw EndOfFile), but nothing stops that.

Exceptions

EndOfFile if there is no more data.

Implements nix::Source.
