However, my intention was that the function which I wrote,
should do what the standard says that atoi does.

atoi is described in terms of what strtol does.
And since strtol is described as 
decomposing the string into three parts,
(the middle one being called "the subject sequence")
and only operating on the subject sequence,
I think that 
    while (isdigit(*nptr)) {
is the way for the code that I wrote,
to do what I want.
