Normally you would read either a fixed chunk of data or a line (i.e.
up to first \n) into a buffer and then use buffer manipulation (string)
manipulation routines to either tokenize or manipulate your data.  For
example, you could use CString::Find tolocate your space.

You can also use the standard C library to achieve what you want:

#include <stdio.h>
int fscanf( FILE *stream, const char *format [, argument ]... );

allows you to read from the file up to a blank.

You probably would prefer to use a C++ technique...

I hope that helps.
