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.
