egd_get_numch - Get the number of channels sampled by type

egd_get_numch()  returns  the number of channels of type stype sampled by the recording device referenced
       by dev. stype must be one of the values returned by egd_sensor_type(3).

egd_get_numch() will fail if:

       EINVALdev is NULL or stype is not valid value.

       egd_get_numch - Get the number of channels sampled by type

       In case of success, the function returns a non negative value corresponding to the number of channels  of
       type  stype  (possibly  0 if the device does not sample this type of data). Otherwise, -1 is returned and
       errno is set accordingly.
