- Method Detail
  - message
```
void message(XpressProblem cbprob,
             java.lang.String msg,
             int msglen,
             int msgtype)
```
    Handle a message event. More details about message events can be found in the documentation of the corresponding C callback.
    Parameters:
    
    cbprob - The problem passed to the callback function.
    
    msg - A null terminated character array (string) containing the message, which may simply be a new line. The total number of bytes (including NUL terminator) will not exceed XPRS_MAXMESSAGELENGTH. If a message needs to be truncated to meet this limit, the last four bytes in msg are set to "...\0".
    
    msglen - The length of the message string, excluding the null terminator.
    
    msgtype - Indicates the type of output message:
    
    1: information messages;
    
    2: (not used);
    
    3: warning messages;
    
    4: error messages.
    
    A negative value indicates that the Optimizer is about to finish and the buffers should be flushed at this time if the output is being redirected to a file.
