RMModifyResources

This rmcall service modifies adapter or device resource sets and also allows for modification of resources owned by an existing adapter or device. Resource handles can be deleted or added to an adapter or device.

Syntax
RMModifyResources(hDriver, hAdapter, ModifyAction, hResource);

Parameters

 * hDriver (HDRIVER) - input : Driver handle of the device driver that created the adapter or device.


 * hAdapter (HADAPTER) - output : Handle of the adapter or device whose resource set is to be modified.


 * ModifyAction (USHORT) - input


 * RM_MODIFY_ADD: Add the resource handle indicated to the adapter or device.
 * RM_MODIFY_DELETE : Delete the resource handle indicated.
 * Deleting a resource implicitly causes an RMDeallocResource to occur; for example, the resource handle is no longer valid.


 * hResource (HRESOURCE) - input : Handle of the resource to be added or deleted.

Return Code

 * rc (APIRET) - returns : On systems where the Resource Manager driver is not installed, the library interface code will return RMRC_NOT_INSTALLED.


 * RMRC_IRQ_ENTRY_ILLEGAL : A Resource Manager service was issued at interrupt time. The Resource Manager service request can be issued only at task time or INIT time.
 * RMRC_BAD_ADAPTERHANDLE : The expected Resource Manager handles were not provided because the handle was not a valid Resource Manager handle or the handle did not point to the type of object the service required.
 * RMRC_BAD_DRIVERHANDLE : The expected Resource Manager handles were not provided because the handle was not a valid Resource Manager handle or the handle did not point to the type of object the service required.
 * RMRC_BAD_RESOURCEHANDLE : The expected Resource Manager handles were not provided because the handle was not a valid Resource Manager handle or the handle did not point to the type of object the service required.
