dio_seek
(PHP 4 >= 4.2.0)
dio_seek -- Seeks to pos on fd from whence
Description
int dio_seek ( resource fd, int pos, int whence)
The function dio_seek() is used to change the file position
of the file with descriptor fd. The parameter whence specifies
how the position pos should be interpreted:
SEEK_SET - specifies that pos is specified from the beginning
of the file.
SEEK_CUR - Specifies that pos is a count of characters
from the current file position. This count may be positive
or negative.
SEEK_END - Specifies that pos is a count of characters
from the end of the file. A negative count specifies a position
within the current extent of the file; a positive count
specifies a position past the current end. If you set the
position past the current end, and actually write data,
you will extend the file with zeros up to that position.
