Function Documentation

NTSTATUS cbmiec_cleanup (  IN PDEVICE_EXTENSION  Pdx  )

Cleanup the IEC bus. This function cleans the IEC bus immediately before it is released. Parameters: Pdx  Pointer to the device extension. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values. Definition at line 193 of file libiec/init.c. References cbmiec_release_bus(), and FUNC_ENTER.

NTSTATUS cbmiec_global_init (  IN PHANDLE  HKey  )

Initialization for libiec which are global in nature. This function initializes libiec. Parameters: HKey  Pointer to a handle with holds a registry key. If this is NULL, no access to the registry is performed. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values. Definition at line 291 of file libiec/init.c. References FUNC_ENTER. Referenced by cbm_init_registry().

NTSTATUS cbmiec_init (  IN PDEVICE_EXTENSION  Pdx  )

Initialize the IEC bus. This function initializes the IEC bus itself, and sets some variables in the device extension. It has to be called before any other IEC function is called. Parameters: Pdx  Pointer to the device extension. Returns: If the routine succeeds, it returns STATUS_SUCCESS. Otherwise, it returns one of the error status values.

Referenced by cbm_lock_parport().

NTSTATUS cbmiec_set_cabletype (  IN PDEVICE_EXTENSION  Pdx, IN IEC_CABLETYPE  CableType )

Set the type of the IEC cable. This function sets the type of the IEC cable. Parameters: Pdx  Pointer to the device extension. CableType  The type of the cable. Definition at line 216 of file libiec/init.c. References FUNC_ENTER. Referenced by cbm_init_registry().
