INT scs400_in_init	(	HNDLE	hKey,
		void **	pinfo,
		INT	channels
	)

Initializes the thermo element MSCB device driver, i.e. generates all the necessary structures in the ODB if necessary, and initializes the MSCB. Furthermore it makes some consitency checks to verify that the addressed module is indeed a thermo element MSCB card.

Return:

FE_SUCCESS if everything went smooth
FE_ERR_ODB otherwise

Parameters

hKey	is the device driver handle given from the class driver
pinfo	is needed to store the internal info structure
channels	is the number of channels of the device (from the class driver)
