Hello,
we know that we can read the lines of a file by using fgetl or fgets. But i need a function that will replace the lines of a file by a string, just the opposite thing of fgetl. is there such a function? doing this work manually is tedious, so i need such a function. please help

It might be possible to do it inplace with memmapfile. If the lines are the same length, etc. I would not try. Try
loop over all lines
fgetl
if
fprintf
else
fprintf
end
end
to a new file
