= CFile =

CFile is a C++ class that is provided to simplify 825 file operations. CFile is a wrapper class around the standard C library FILE object. CFile also provides some useful features such as baud rate setting for the 825 serial ports.

== Constructors ==

 * CFile(void);
 * CFile(const string& strFilename);
 * CFile(const char* pszfilename);

These constructors just create a CFile object without opening a file.

 * CFile(const string& strFilename, const string& strMode);
 * CFile(const string& strFilename, const char* pszMode);
 * CFile(const char* pszFilename, const string& strMode);
 * CFile(const char* pszFilename, const char* pszMode);

These constructors construct the file object and attempt to open the file.

{{{
CFile fileLog("/mnt/fl1/log.txt", "a");
if(fileLog.IsOpen())
{
     fileLog.Print("Gross %s Tare %s Net %s\r\n", FormatGrossWt(1).c_str(), FormatTareWt(1).c_str(), FormatNetWt(1).c_str()); 
     fileLog.Close();
}
}}}

== Member Functions ==

=== Open ===
Opens a specified file, or using the filename already stored in the object.

 * bool Open(const string& strFilename, const string& strMode);
 * bool Open(const string& strFilename, const char* pszMode);
 * bool Open(const char* pszFilename, const string& strMode);
 * bool Open(const char* pszFilename, const char* pszMode);
 * bool Open(const char* pszMode);

==== Parameters ====
 * strFilename - filename
 * pszFilename - filename
 * strMode - mode
 * pszMode - mode

==== Return ====

Returns true if successful or false if unsuccessful.


=== Close ===
Closes the file
 * void Close(void);

==== Parameters ====

Function does not accept any parameters
