Namespaces
namespace	chomp
	This namespace contains the entire CHomP library interface.
namespace	chomp::multiwork
	This namespace contains an interface to the MultiWork module which allows one to easily distribute a computational task over multiple processes and run concurrent computations.
Enumerations
enum	chomp::multiwork::mwIOconstants {   chomp::multiwork::mwNone = 0, chomp::multiwork::mwCanRead = 0x01, chomp::multiwork::mwCanWrite = 0x02, chomp::multiwork::mwTimeOut = -4,   chomp::multiwork::mwLost = -5 }
	Input/output flags and error codes used for network communication, mainly for the 'select' function to check which sockets are available for reading/writing. More...
Functions
int	chomp::multiwork::mwSendBytes (int fd, const char *buf, int len)
	Sends the given buffer to the given socket.
int	chomp::multiwork::mwRecvBytes (int fd, char *buf, int len)
	Receives the given amount of data from the given socket.
int	chomp::multiwork::mwConnect (const char *name, int port)
	Connects to the given computer at the given port.
int	chomp::multiwork::mwListen (int port, int queuesize)
	Begins listening at the given port.
int	chomp::multiwork::mwAccept (int fd, std::string &computer, int timeout=-1)
	Waits for and accepts a connection at the given socket.
int	chomp::multiwork::mwSelect (const int *workers, int nworkers, int listensocket, int *ioflags, int timeout)
	Determines IOflags for each of the workers and additionally the listensocket (the last flag).
void	chomp::multiwork::mwDisconnect (int fd)
	Disconnects the given socket.
