r+b filemode

[Oleg Moroz]

Hello everyone, i have a trouble with opening file. i have opened the file with "wb" mode. Write to it 512 bytes. close it. after this open it with "r+b" mode. then trying:

/// 
fseek(file,0,SEEK_END);
int i = ftell(file);
///



after this i=0

but when i'm opening file with "rb" mode - i=512. how i can use "r+b" mode?
