- 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.
