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 resource. 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
