Detailed Description

Provides a fc::thread friendly cooperatively multi-tasked stream that will block 'cooperatively' instead of hard blocking.

◆ read() [1/2]

istream & fc::istream::read ( char *  buf,
size_t  len 

read len bytes or throw, this method is implemented in terms of readsome.

fc::eof_exceptionif len bytes cannot be read

◆ read() [2/2]

istream & fc::istream::read ( const std::shared_ptr< char > &  buf,
size_t  len,
size_t  offset = 0 

Definition at line 282 of file iostream.cpp.

◆ readsome() [1/2]

virtual size_t fc::istream::readsome ( char *  buf,
size_t  len 
pure virtual

read at least 1 byte or throw, if no data is available this method should block cooperatively until data is available or fc::eof is thrown.

fc::eofif at least 1 byte cannot be read

Implemented in graphene::net::stcp_socket, fc::tcp_socket, fc::asio::istream< AsyncReadStream >, fc::ifstream, fc::buffered_istream, fc::cin_t, and fc::stringstream.
