/********************************************************************
Name: test_dimensions()
Description:
This test routine is used to test various dimension operations.
The main contents include:
- creates the file dim.hdf
- creates an SDS of size 15 x 10, and sets values to its dimensions
- creates another SDS of size 4 x 3, and sets values to its
first dimension
The followings are included in this test routine:
- SDgetdimid
- SDsetdimname
- SDdiminfo
- SDgetdimscale
- SDsetdimscale with the following situations:
+ not called before SDdiminfo
+ called with number type = 0
+ called with an unsigned number type
+ called with the dataset's number type
+ called before writing data to dataset
+ called after closing dataset and file, and then
reopening
Return value:
The number of errors occurred in this routine.
