Detailed Description

Holds all information about a user This class stores all information about a user connected to the irc server.

Everything about a connection is stored here primarily, from the user's socket ID (file descriptor) through to the user's nickname and hostname. Use the Find method of the server class to locate a specific user by nickname.

bool userrec::AddBuffer (  std::string  a  ) 
 

This method adds data to the buffer of the user.

The buffer can grow to any size within limits of the available memory, managed by the size of a std::string, however if any individual line in the buffer grows over 600 bytes in length (which is 88 chars over the RFC-specified limit per line) then the method will return false and the text will not be inserted.

bool userrec::BufferIsReady (   ) 
 

This method returns true if the buffer contains at least one carriage return character (e.g.

one complete line may be read)

std::string userrec::GetBuffer (   ) 
 

This method returns the first available string at the tail end of the buffer and advances the tail end of the buffer past the string.

This means it is a one way operation in a similar way to strtok(), and multiple calls return multiple lines if they are available. The results of this function if there are no lines to be read are unknown, always use BufferIsReady() to check if it is ok to read the buffer before calling GetBuffer().

char * userrec::GetFullRealHost (   )  [virtual]
 

Returns the full real host of the user This member function returns the hostname of the user as seen by other users on the server, in nick!identhost form.
