Public Methods

protocol_stream( SOCKET sock, int gen_timeout )

at the beginning set the everything_read to false, because we have prompt

protocol_stream& operator >>( std::string &s )

s will remains empty only if it is nothing to read

protocol_stream& operator >>( int &value )

assume that there are nothing on that string except this integer, this is simplification of protocol, be warned

protocol_stream& operator >>( std::vector< std::string > &lines )

download everything between -> and <-

protocol_stream& operator <<( const std::string &s )

void wait_input()

we know that input is available

bool test_for_input( int millisec )

bool test_for_any_pending_input( int millisec )

test not only socket, but the buffer as well

bool is_command( const std::string &s )

test if s is equal to the word 'command'

ifdef WIN32 bool buffer_is_empty()

bool eof()

int peek()

returns -1 if no input, or the next char

int get( char &location )

char* getline( char *buf, unsigned size )

void skip_to_prompt()

before reading, check for everything_read flag

void skip_to_prompt( std::vector< std::string > &messages )

void append_messages( std::vector< std::string > &msgs )

returns -1 if no input, or the next char

int get( char &location )

char* getline( char *buf, unsigned size )

void skip_to_prompt()

before reading, check for everything_read flag. If nothing to wait from input, return. After sending the command that should return something, user must call wait_input, which indicates that sequence of -> and <- should appear in input before '>>>'
