- This command reads the next line from the file given by _f_i_l_e_I_d and
- discards the terminating newline character. If _v_a_r_N_a_m_e is specified then
- the line is placed in the variable by that name and the return value is a
- count of the number of characters read (not including the newline). If
- the end of the file is reached before reading any characters then -1 is
- returned and _v_a_r_N_a_m_e is set to an empty string. If _v_a_r_N_a_m_e is not
- specified then the return value will be the line (minus the newline
- character) or an empty string if the end of the file is reached before
- reading any characters. An empty string will also be returned if a line
- contains no characters except the newline, so eeeeooooffff may have to be used to
- determine what really happened. If the last character in the file is not
- a newline character then ggggeeeettttssss behaves as if there were an additional
- newline character at the end of the file. _F_i_l_e_I_d must be ssssttttddddiiiinnnn or the
- return value from a previous call to ooooppppeeeennnn; it must refer to a file that
- was opened for reading. Any existing end-of-file or error condition on |
- the file is cleared at the beginning of the ggggeeeettttssss command.
