KsAcquireControl function (ks.h)
The KsAcquireControl function acquires the filter control mutex for Object.
Syntax
void KsAcquireControl(
[in] PVOID Object
);
Parameters
[in] Object
A pointer to the object for which to acquire the filter control mutex. This should be a pointer to either a KSFILTER or a KSPIN, cast to PVOID.
Return value
None
Remarks
Minidrivers typically do not call this function directly, but instead call either KsFilterAcquireControl or KsPinAcquireControl. These functions provide the necessary typecasting to PVOID automatically.
