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
.
