The getdelim function is a more general form of the
getline function; whereas getline stops reading input at
the first newline character it encounters, the getdelim function
enables you to specify other delimiter characters than newline. In
fact, getline simply calls getdelim and specifies that the
delimiter character is a newline.
The syntax for getdelim is nearly the same as that of
getline, except that the third parameter specifies the delimiter
character, and the fourth parameter is the stream from which to read.
You can exactly duplicate the getline example in the last section
with getdelim, by replacing the line
