I'm new to C and am using fseek. My question is, what exactly does it do?
eg: fseek(FILE *stream, -1, SEEK_CUR) will read 1 character backwards, so is it already at the end of the file?
Does that mean fseek(FILE *stream, 0, SEEK_CUR) does nothing?
And how do we apply the functions after fseek to a data structure?
