The SCATGATH Sample accompanies Chapter 7 and illustrates how to program a DMA transfer for a PCI bus-mastering device having scatter/gather capability.
The sample includes one component:
To build SCATGATH.SYS, follow the general instructions for building a WDM sample. The Microsoft Visual C++ project file is named SCATGATH.DSP.
SCATGATH doesn’t have a test program. I put it into the book in order to verify that the code examples used in the text would actually compile successfully.
