Detailed Description

A class to serialize HDF calls for multithreaded apps.

Since the HDF4 libraries aren't thread-safe, it's necessary to make sure that two threads don't use HDF routines concurrently. This class starts an I/O thread and passes HDF commands to it. It also provides a few utility functions, and supports caching of open file descriptors.

"Open" and "close" HDF files efficiently.

The "single file" SD routines add several "fake" datasets, which severely clutter up the file and complicate searches.

Select the first non-"fakeDim" dataset, starting at index.

This more powerful version of SDselect adds the functionality of SDgetinfo and ignores fake datasets.

Parameters
indexThe index of the dataset to select. The difference from SDselect is that this parameter will be assigned the index of the first non-"fake" dataset (possibly the initial value).
dsCountThe number of datasets in the file. If this isn't provided, the number of datasets is determined by calling SDfileinfo.
Returns
An HDF4 dataset id on success, or FAIL on failure.
Note
See the documentation for SDselect and SDgetinfo for the descriptions of the other parameters.

Get the size in bytes of an HDF data type.

Like the "sizeof" operator, except that this takes a HDF4 datatype id.

Parameters
dTypeThe HDF4 datatype id.
Returns
