fread() behaves weird
- by Cres
hi,
I have a problem in a C program of mine where after I use fread(), the file pointer goes to the end of the file sometimes.
I'll try to explain better - the code looks something like:
dummy = ftell(fp);
fread(&buf, sizeof(unsigned char), 8, fp);
dummy = ftell(fp);
where fp is a file pointer to an opened file (opened it with "w+", I'm using it as a binary file and I know i'm supposed to have a "b" in there too, but I heard its not really important to add it..),
dummy is just an unsigned long variable,
and buf is unsigned char[8]
now, when debugging, at the ftell before the fread, dummy is 262062
at the ftell after the fread, dummy is 262640
even though I only 'moved' 8 bytes..
does anyone have any idea what can be the cause of this..?
thanks for your help :)
