hdf5/test/tselect.c
Quincey Koziol b0e350c2d6 [svn-r7259] Purpose: 
Bug fix

Description:
    I/O on chunked datasets with point selections was not working correctly.

Solution:
    Re-wrote some parts of raw data I/O routines that build the selections for
    each chunk to correctly handle point selections.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
