The CM_Get_First_Log_Conf function obtains the first logical configuration, of a specified configuration type, associated with a specified device instance on the local machine.
Address of a location to receive the handle to a logical configuration, or NULL. See the following Remarks section.
Caller-supplied device instance handle that is bound to the local machine.
Caller-supplied flag value indicating the type of logical configuration being requested. One of the flags in the following table must be specified.
Configuration Type Flags | Definitions |
---|---|
BASIC_LOG_CONF | The caller is requesting basic configuration information. |
FILTERED_LOG_CONF | The caller is requesting filtered configuration information. |
ALLOC_LOG_CONF | The caller is requesting allocated configuration information. |
BOOT_LOG_CONF | The caller is requesting boot configuration information. |
FORCED_LOG_CONF | The caller is requesting forced configuration information. |
OVERRIDE_LOG_CONF | The caller is requesting override configuration information. |
If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.
Calling CM_Add_Empty_Log_Conf or CM_Free_Log_Conf can invalidate the handle obtained from a previous call to CM_Get_First_Log_Conf. Thus if you want to obtain logical configurations after calling CM_Add_Empty_Log_Conf or CM_Free_Log_Conf, your code must call CM_Get_First_Log_Conf again and start at the first configuration.
The handle received in plcLogConf must be explicitly freed by calling CM_Free_Log_Conf_Handle.
If CM_Get_First_Log_Conf is called with plcLogConf set to NULL, no handle is returned. This allows you to use the return status to determine if a configuration exists without the need to subsequently free the handle.
For information about using device instance handles that are bound to the local machine, see CM_Get_Child.
