This SDK includes a number of sample applications. Each sample documents a feature of the SDK in both prose and the associated C code. The following samples are included:
In addition, the SDK contains a number of utilities. Since these utilities are built upon the concepts described in the sample code listed above, they are not documented in pieces like the samples are. Their source is included here for reference. The following utilities are included:
