CErrnoException

Name

CErrnoException -- Exceptions that wrap the Unix errno

Synopsis


#include <ErrnoException.h>
class           CErrnoException {
                
  CErrnoException(const pszAction);
                  CErrnoException(const std::string& rsAction);
                
  virtual   const const char* ReasonText();
                  virtual const Int_t ReasonCode();
};

Description

This exception class wraps the Unix errno global variable. errno is used by most Unix system calls to provide detailed status information. Constructing this class saves a copy of the errno variable. ReasonCode will return the saved errno value. ReasonText will construct a string that includes the text associated with the errno.

Public member functions

CErrnoException(const pszAction); CErrnoException(const std::string& rsAction);

These constructors save the value of the errno variable and construct the base class using their parameter as the exception context string (returned by WasDoing).

virtual const const char* ReasonText();

Returns the sterror applied to the saved errno.

virtual const Int_t ReasonCode();

Returns the saved errno variable value.
