Change the current access position for _f_i_l_e_I_d. _F_i_l_e_I_d must
have been the return value from a previous call to ooooppppeeeennnn, or
it may be ssssttttddddiiiinnnn, ssssttttddddoooouuuutttt, or ssssttttddddeeeerrrrrrrr to refer to one of the
standard I/O channels. The _o_f_f_s_e_t and _o_r_i_g_i_n arguments
specify the position at which the next read or write will
occur for _f_i_l_e_I_d. _O_f_f_s_e_t must be an integer (which may be
negative) and _o_r_i_g_i_n must be one of the following:
ssssttttaaaarrrrtttt
The new access position will be _o_f_f_s_e_t bytes from the
start of the file.
ccccuuuurrrrrrrreeeennnntttt
The new access position will be _o_f_f_s_e_t bytes from the
current access position; a negative _o_f_f_s_e_t moves the
access position backwards in the file.
eeeennnndddd The new access position will be _o_f_f_s_e_t bytes from the
end of the file. A negative _o_f_f_s_e_t places the access
position before the end-of-file, and a positive _o_f_f_s_e_t
places the access position after the end-of-file.
The _o_r_i_g_i_n argument defaults to ssssttttaaaarrrrtttt. This command returns
an empty string.
