IoWithinStackLimits function (wdm.h)
The IoWithinStackLimits routine determines whether a region of memory is within the stack limit of the current thread.
Syntax
LOGICAL IoWithinStackLimits(
[in] ULONG_PTR RegionStart,
[in] SIZE_T RegionSize
);
Parameters
[in] RegionStart
A pointer to the start of the region.
[in] RegionSize
The size of the region.
Return value
IoWithinStackLimits returns TRUE is the current thread's stack contains the region completely and FALSE otherwise.
Remarks
The IoWithinStackLimits routine considers all possible stack segments and the DPC stack, if necessary.
For drivers that use KeExpandKernelStackAndCallout, IoWithinStackLimits considers only the current thread.
