odd behaviour of fread

[kedaman]

Two things, fread reads 1 byte when its suppose to read 4, but get no errors nor has it reached end of file, and the other thing is that it jumps to 245, can anyone explain this?

getpos(f,&pos);
Debug << pos <<endl;// says 0

size_t s;Debug<<fread(&s,sizeof(size_t),1,f)<<endl;_node.resize(s);//says 1

Debug<<ferror(f)<<endl;//says 0

Debug<<feof(f)<<endl;//says 0

fgetpos(f,&pos);

Debug << pos <<endl;//says 245

fread(&s,sizeof(size_t),1,f);_edge.resize(s);

Your code is a mess.
But, if it says 245 then it is jumpin that far. Are you sure the struct in the first read isn't 245 bytes large?? 245 is a weird one to end up as well especially if you are using MSVC since padding keeps it all to divisible by DWORD.

The fread return value is fine:

fread returns the number of full items actually read,

Does fgetpos return 0?

i ditched fread some time ago, and switched to ifstream, works better now, thanks for answering anyway
