seek
seek filehandle , offset , whence
Positions the file pointer for
filehandle
, just
like the
fseek(3)
call of standard I/O. The first position in a
file is at offset
0
, not offset
1
, and offsets refer to byte positions,
not line numbers.
The function returns
1
upon success,
0
otherwise.
For handiness, the function can calculate offsets from various file
positions for you. The value of
whence
specifies which of three file
positions your
offset
is relative to:
0
, the beginning of
the file;
1
, the current position in the file; or
2
, the
end of the file.
offset
may be negative for a
whence
of
1
or
2
.
