    saving data into a file

    Hi every1!
    Im implementing a web cache, and i've a buffer which has the data of a specific file, when i want to write it into a file. It works for text/plain data, but when i use images it doesnt work. For example, im doing something like this:

    FILE* fp;
    fp = fopen("mypicture.jpg","wb");

    is there anykind of processing i must do everytime i use image files?

    Please define "it doesn't work".

    is the file already open by some other process? If it is, then your program cannot open it for output. Otherwise that open statements should work ok for any type of file.
