Gets the breakpoint request information that describes this breakpoint request.
Syntax
HRESULT GetRequestInfo(
BPREQI_FIELDS dwFields,
BP_REQUEST_INFO* pBPRequestInfo
);
int GetRequestInfo(
eunm_BPREQI_FIELDS dwFields,
BP_REQUEST_INFO[] pBPRequestInfo
);
Parameters
dwFields
[in] A combination of flags from the BPREQI_FIELDS enumeration that determines which fields in the pBPRequestInfo parameter are to be filled out.
pBPRequestInfo
[out] Specifies the BP_REQUEST_INFO structure to be filled in with the description of the breakpoint request.
Return Value
If successful, returns S_OK; otherwise, returns an error code.
Example
The following example shows how to implement this method for a simple CDebugBreakpointRequest object that exposes the IDebugBreakpointRequest2 interface.

BPREQI_FIELDS dwFields,
BP_REQUEST_INFO* pBPRequestInfo)

// Copy the specified fields of the request info from the class
// member variable to the local BP_REQUEST_INFO variable.

*pBPRequestInfo, dwFields);
}
else
{
hr = E_INVALIDARG;
}
