ICLRGCManager2::SetGCStartupLimitsEx Method

Sets the size of a garbage collection segment and the maximum size of the garbage collection system's generation 0.

Syntax

HRESULT SetGCStartupLimitsEx (  
    [in] SIZE_T SegmentSize,
    [in] SIZE_T MaxGen0Size  
);

Parameters

SegmentSize
[in] The specified size of a garbage collection segment.

The minimum segment size is 4 MB. Segments can be increased in increments of 1 MB or larger.

MaxGen0Size
[in] The specified maximum size for generation 0.

The minimum generation 0 size is 64 KB.

Return Value

HRESULT Description
S_OK SetGCStartupLimitsEx returned successfully.
HOST_E_CLRNOTAVAILABLE The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL An unknown catastrophic failure occurred. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

Remarks

The values that SetGCStartupLimitsEx sets can be specified only before the host is started. Later calls to SetGCStartupLimitsEx are ignored.

To set either parameter without affecting the other, specify 0 (zero) for the parameter you don't want to change.
