Does fgets () move the file pointer?

Does the fgets () function automatically move the file pointer to the position before the parameter value I specified?

eg:

the content of the p.txt file is "I'm a good boy". After using fgets (a, 5, fp1) does the file pointer move forward 5 positions?

Couldn't find this in any book. Hence the request.

The pointer fp1

does not affect the call fgets

(or any other I / O procedure stdio

); The object FILE

that is pointing fp1

will be updated to reflect the new file position, but the pointer itself does not change.

The file pointer is not changed by the function fgets

.



However, the file offset increases by the number of bytes actually read.
