get binary data in binary file

[fat_man]

I know how to open a binary file with fopen('abc.dat', 'rb') but I don't how to get the data from it.

I know the position (offset) of some long, interget, char and string. However I fail to get them by any method. I had trial fread, fgetc and fgets and fscanf but all false.

Is there any function I was overlooked?
