DESCRIPTION
Objects of type <<FILE>> can have a ``position'' that records how much
of the file your program has already read. Many of the <<stdio>> functions
depend on this position, and many change it as a side effect.
You can use <<fseeko64>> to set the position for the file identified by
<[fp]> that was opened via <<fopen64>>. The value of <[offset]> determines
the new position, in one of three ways selected by the value of <[whence]>

(defined as macros in `<<stdio.h>>'):
<<SEEK_SET>>---<[offset]> is the absolute file position (an offset
from the beginning of the file) desired. <[offset]> must be positive.
<<SEEK_CUR>>---<[offset]> is relative to the current file position.
<[offset]> can meaningfully be either positive or negative.
<<SEEK_END>>---<[offset]> is relative to the current end of file.
<[offset]> can meaningfully be either positive (to increase the size
of the file) or negative.
See <<ftello64>> to determine the current file position.
RETURNS
<<fseeko64>> returns <<0>> when successful. On failure, the
result is <<EOF>>. The reason for failure is indicated in <<errno>>:
either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
repositioning or wasn't opened via <<fopen64>>) or <<EINVAL>>
