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
.
