PsSwitchCpu

Switches to a different CPU core.

Syntax

PULSE_STATUS PsSwitchCpu(
[in] PPS_ENGINE pEngine,
[in] uint64_t TargetCpuIndex
);

PPS_ENGINE pEngine

An opaque handle to an engine created by the EngCreateEngine function.

uint64_t TargetCpuIndex

The index of the CPU core to be switched to making it the current CPU core.

If the function succeeds, the return value is PULSE_STATUS_SUCCESS.

If it fails, it returns one of the PULSE_STATUS values. Possible return codes include, but are not limited to, the following:

PULSE_STATUS_BARRIER_ALREADY_OWNED 0x00000021	The target CPU core is already the current one.
PULSE_STATUS_INSUFFICIENT_RESOURCES 0xC0000002	One of the memory allocations failed during initialization.
PULSE_STATUS_READ_FAILED 0xC0000003	Transport communication failed during a read operation.
PULSE_STATUS_WRITE_FAILED 0xC0000004	Transport communication failed during a write operation.
PULSE_STATUS_TIMEOUT 0xC0000007	Might happen if Transport I/O timed out. No response was received from the debuggee within the request timeout period.
PULSE_STATUS_INVALID_PARAMETER 0xC0000010	The pEngine parameter is NULL.
PULSE_STATUS_INVALID_PACKET 0xC0000031	An invalid or unexpected packet was received in response.
PULSE_STATUS_BARRIER_OWNER_INACTIVE 0xC0000043	The target CPU core cannot be run at this time. It might be shut down or not started yet.
PULSE_STATUS_BARRIER_NO_CPU 0xC0000044	The target CPU core does not exist. Check the target parameter.
PULSE_STATUS_DEVICE_CONNECTION_LOST 0xC0000308	The connection to the transport was lost. Try restarting the engine or the transport.

Calling this function while the debug target is active will produce undefined behavior.
