Name
seek
Synopsis
seek filehandle, offset, whence
Description
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
.
