Toggles the virtualized state of this pending breakpoint. When a pending breakpoint is virtualized, the debug engine will attempt to bind it every time new code loads into the program.

Syntax

HRESULT Virtualize(
    BOOL fVirtualize
);

int Virtualize(
    int fVirtualize
);

Parameters

fVirtualize
[in] Set to nonzero (TRUE) to virtualize the pending breakpoint, or to zero (FALSE) to turn off virtualization.

Return Value

If successful, returns S_OK; otherwise, returns an error code. Returns E_BP_DELETED if the breakpoint has been deleted.

Remarks

A virtualized breakpoint is bound every time code is loaded.

Example

The following example shows how to implement this method for a simple CPendingBreakpoint object that exposes the IDebugPendingBreakpoint2 interface.

HRESULT CPendingBreakpoint::Virtualize(BOOL fVirtualize)
{
    HRESULT hr;

    // Verify that the pending breakpoint has not been deleted. If deleted,
    // then return hr = E_BP_DELETED.
    if (m_state.state != PBPS_DELETED)
    {
        if (fVirtualize)
        {
            // Set the PBPSF_VIRTUALIZED flag in the PENDING_BP_STATE_FLAGS
            // structure.
            SetFlag(m_state.flags, PBPSF_VIRTUALIZED);
        }
        else
        {
            // Clear the PBPSF_VIRTUALIZED flag in the PENDING_BP_STATE_FLAGS
            // structure.
            ClearFlag(m_state.flags, PBPSF_VIRTUALIZED);
        }
        hr = S_OK;
    }
    else
    {
        hr = E_BP_DELETED;
    }

    return hr;
}
