// Function: MyRasGetEntryProperties()
//
// Synopsis: Performs some buffer size checks and then calls RasGetEntryProperties()
// See the RasGetEntryProperties() docs to understand why this is needed.
//
// Arguments: Same as RasGetEntryProperties with the following exceptions:
// lplpRasEntryBuff -- pointer to a pointer to a RASENTRY struct. On successfull
// return, *lplpRasEntryBuff will point to the RASENTRY struct
// and buffer returned by RasGetEntryProperties.
// NOTE: should not have memory allocated to it at call time!
// To emphasize this point, *lplpRasEntryBuff must be NULL
// lplpRasDevInfoBuff -- pointer to a pointer to a RASDEVINFO struct. On successfull
// return, *lplpRasDevInfoBuff will point to the RASDEVINFO struct
// and buffer returned by RasGetEntryProperties.
// NOTE: should not have memory allocated to it at call time!
// To emphasize this point, *lplpRasDevInfoBuff must be NULL
// NOTE: Even on a successfull call to RasGetEntryProperties,
// *lplpRasDevInfoBuff may return with a value of NULL
// (occurs when there is no extra device info)
//
// Returns: ERROR_NOT_ENOUGH_MEMORY if unable to allocate either RASENTRY or RASDEVINFO buffer
// Otherwise, it retuns the error code from the call to RasGetEntryProperties.
// NOTE: if return is anything other than ERROR_SUCCESS, *lplpRasDevInfoBuff and
// *lplpRasEntryBuff will be NULL,
// and *lpdwRasEntryBuffSize and *lpdwRasDevInfoBuffSize will be 0
//
// Example:
//
// LPRASENTRY lpRasEntry = NULL;
// LPRASDEVINFO lpRasDevInfo = NULL;
// DWORD dwRasEntrySize, dwRasDevInfoSize;
//
// hr = MyRasGetEntryProperties( NULL,
// g_pcDialErr->m_pszConnectoid,
// &lpRasEntry,
// &dwRasEntrySize,
// &lpRasDevInfo,
// &dwRasDevInfoSize);
//
//
// if (hr != ERROR_SUCCESS)
// {
// //handle errors here
// } else
// {
// //continue processing
// }
