View the official Windows Driver Kit DDI referenceNo description available.
The FsRtlPostPagingFileStackOverflow routine posts a paging file stack overflow item to the stack overflow thread.
Context [in]A context pointer to pass to the stack overflow callback routine.
Event [in]A pointer to a caller-allocated notification event to pass to the stack overflow callback routine. Must have been initialized as nonsignaled by calling KeInitializeEvent.
StackOverflowRoutine [in]A pointer to a callback routine to be invoked when processing the request in the overflow thread.
A file system typically calls FsRtlPostPagingFileStackOverflow during a paging file I/O operation when the amount of remaining stack space returned by IoGetRemainingStackSize is below the file system's stack overflow read threshold. FsRtlPostPagingFileStackOverflow posts the paging I/O request to a special paging stack overflow work queue. When the paging I/O operation has been completed, the caller's Event is set to a signaled state.
Note Warning: File system filter drivers must never call FsRtlPostPagingFileStackOverflow, because doing so can halt the forward progress of paging file I/O operations.
