When I wrote my first article on CodeGuru,
Expandable, Data Type-Neutral Buffer Class,
I realized that there are lot of people seeking the code
for a circular file.
Hence, I developed my own circular file implementation, and want
to share this. Its interface is very simple. Everything basically
revolves around the Addline(CString) method which you use to
add a line at a time to the current file.
//Create New File with Name "default Log" with 100 Lines
//Create File with Name strFile Name But 100 lines
CCirFile(char * strFileName);
//You can specify file Name and File Size
CCirFile(char * ,int );
//All file initialization here
//You should call this function to add new line at start of file
int AddLine( CString );
It's not a true circular file implementation.
It adds each new line to the beginning of the file,
and moves the remaining lines, truncating the last line
It's slow and performance could be dramatically increased via
the use of multiple threads.
