.PP 
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.

This method adds data to the buffer of the user.

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 \fBBufferIsReady()\fP to check if it is ok to read the buffer before calling \fBGetBuffer()\fP.Definition at line 208 of file users.cpp.
