binding handle that connects to the RPC interface of the Firewall and Advanced
Security Protocol.</p><p><b>BinaryVersion: </b>This parameter specifies the
RPC interface binary version. This implies versions of the methods and versions
of the structures.</p><p><b>StoreType: </b>This parameter specifies the policy
store in which the client wants to modify this configuration option.</p><p><b>configID: </b>This parameter specifies the
specific global policy configuration option the client wants to modify.</p><p><b>lpBuffer: </b>This is an input parameter. This
parameter is a pointer to the buffer that the client provides containing the
value to write on the configuration option specified. If the buffer is NULL,
this method deletes the configuration option.</p><p><b>dwBufSize: </b>This parameter is the size of the
buffer to which the <i>lpBuffer</i> parameter points.</p><p><b>Return Values: </b>The method returns 0 if
successful; if failed, it returns a nonzero error code. The field can take any

  <td>One of the parameters of this method is incorrect, or is required and not specified. This error can be returned because:  The specific configuration option is not meant to be available in the specified store.  The specified configuration option is not defined.  One of the required values is not specified.  The buffer is null but dwBufSize says otherwise.  The buffer size is not enough to hold the specific value.</td>
