How to tell getline to stop at a specific string...

[GGrrl]

...hello again ladies and gentlemen...this is my problem...it is probably dumb and of trivial nature...but I cannot find any guidance elsewhere...
...the entire text file I am working with is composed of documents that are separated by '\\\\\'...I need to separate these...how do I tell the program that every time it reads '\\\\\' it needs to increment the counter and store what it has read so far into a data structure that I have created?...so far I am using fstream...reading the file fine with the getline function...but I cannot figure out how to tell it to notice this '\\\\\'...any help would be greatly appreciated...

how big is the file? you could read the entire thing in and use the 'strstr()' function to parse the sections yourself.

...I will attempt that thank you so much...
