read from file from the beginning?

Hello

How can I force fgets (in c) to begin reading form a specific offset? to be more exact, i need to read from the beginning of the file (every time i issue a fgets command), without closing the file and reopening. So i need to reset the file read pointer somehow...

How is that done?

thanks

You would use fseek. Take a look at the man page and if you have any questions post them.

fseek and its happy family: visit them at "man fseek" ;-)

use Function int fseek (FILE *stream, long int offset, int whence)
as
int fseek(FILE *stream,0,SEEK_SET);
before using fgets;

oops same happened with me.
