The SWSTARTUPINFO contains information about a client program's instance data.

Fields

sisVersion

Not used.

sisNextDev

Specifies the 32-bit address (segment:offset) of the next structure in the client chain.

sisVirtDevFile

Not used.

sisReferenceData

Not used.

sisInstanceData

Specifies the 32-bit address (segment:offset) of a list of SWINSTANCEITEM structures, each of which describes one contiguous block of instance data. The list is terminated by a 32-bit zero value.

Comments

This structure is also used with the Microsoft Windows startup Interrupt 2Fh function. However, task switchers use only the sisNextDev and sisInstanceData fields. For detailed information about the other fields in the SWSTARTUPINFO structure, see the Microsoft Windows Device Driver Kit Virtual Device Adaptation Guide.
