ICLRGCManager::SetGCStartupLimits Method

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

Important note Important

Starting with the .NET Framework 4.5, you can set segment size and maximum generation 0 size to values greater than DWORD by using the ICLRGCManager2::SetGCStartupLimitsEx method.

HRESULT SetGCStartupLimits (
    [in] DWORD SegmentSize, 
    [in] DWORD MaxGen0Size
);

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.

HRESULT

Description

S_OK

SetGCStartupLimits 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.

The values that SetGCStartupLimits sets can be specified only once. Later calls to SetGCStartupLimits are ignored.
