ResourceClearCpuBoosting(ResourcePidInfo)

Clears cpu boosting for the boosted process (pid/tids).

Declaration
public static void ResourceClearCpuBoosting(ResourcePidInfo pid)
Parameters
Type Name Description
ResourcePidInfo pid

The target process pid/tids.
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not.

Examples
Resource.ResourceClearCpuBoosting(new ResourcePidInfo() { Pid = processInfo.Id });

ResourceClearCpuInheritance(int, string)

Clears cpu resource inheritance from the source tid to the destination process (pid/tids).

Declaration
public static void ResourceClearCpuInheritance(int sourceTid, string destProcess)
Parameters
Type Name Description
int sourceTid

The caller thread tid.
string destProcess

The name of destination process.
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not. It should be called from source after calling the resource_register_cpu_inheritance_destination() function in the destination.

Examples
Resource.ResourceClearCpuInheritance(0, "test-destination");

ResourceGetCpuBoostingLevel(ResourcePidInfo, out CpuBoostingLevelInfo)

Gets the cpu boosting level for the target process (pid/tids).

Declaration
public static void ResourceGetCpuBoostingLevel(ResourcePidInfo pid, out CpuBoostingLevelInfo level)
Parameters
Type Name Description
ResourcePidInfo pid

The target process pid/tids.
CpuBoostingLevelInfo level

The boosting level for the target process (pid/tids).
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not.

Examples
CpuBoostingLevelInfo level = new CpuBoostingLevelInfo();
Resource.ResourceGetCpuBoostingLevel(new ResourcePidInfo() { Pid = processInfo.Id }, out level);

ResourceRegisterCpuInheritanceDestination(string, ResourcePidInfo)

Registers a destination process (pid/tids) for cpu resource inheritance.

Declaration
public static void ResourceRegisterCpuInheritanceDestination(string destProcess, ResourcePidInfo pid)
Parameters
Type Name Description
string destProcess

The name of destination process.
ResourcePidInfo pid

The destination process pid/tids.
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not.

Examples
Resource.ResourceRegisterCpuInheritanceDestination("test-destination", new ResourcePidInfo() { Pid = processInfo.Id });

ResourceSetCpuBoosting(ResourcePidInfo, CpuBoostingLevel, CpuBoostingFlag, int)

Sets cpu boosting for the target process (pid/tids) to the desired level for as long as required.

Declaration
public static void ResourceSetCpuBoosting(ResourcePidInfo pid, CpuBoostingLevel level, CpuBoostingFlag flags, int timeoutMsec)
Parameters
Type Name Description
ResourcePidInfo pid

The target process pid/tids.
CpuBoostingLevel level

The cpu boosting level
CpuBoostingFlag flags

The cpu boosting flag bits
int timeoutMsec

The timeout in milliseconds
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not.

Examples
Resource.ResourceSetCpuBoosting(new ResourcePidInfo() { Pid = processInfo.Id }, CpuBoostingLevel.CpuBoostingLevelStrong, 0, -1);

ResourceSetCpuInheritance(int, string, int)

Sets cpu resource inheritance from the source tid to the destination process (pid/tids).

Declaration
public static void ResourceSetCpuInheritance(int sourceTid, string destProcess, int timeoutMsec)
Parameters
Type Name Description
int sourceTid

The caller thread tid.
string destProcess

The name of destination process.
int timeoutMsec

The timeout in milliceconds.
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not. It should be called from source after calling the resource_register_cpu_inheritance_destination() function in the destination.

Examples
Resource.ResourceSetCpuInheritance(0, "test-destination", 500);

ResourceUnregisterCpuInheritanceDestination(string)

Unregisters a destination process (pid/tids) for cpu resource inheritance.

Declaration
public static void ResourceUnregisterCpuInheritanceDestination(string destProcess)
Parameters
Type Name Description
string destProcess

The name of destination process.
Remarks

An internal API, so it can be used only by partner level developers. In addition, the developers cannot arbitrary choose whether to enforce this privilege or not.

Examples
Resource.ResourceUnregisterCpuInheritanceDestination("test-destination");
