NAME

       egd_sensor_type, egd_sensor_name - Get the id or name of a sensor type

SYNOPSIS

       #include <eegdev.h>

       int egd_sensor_type(const char* sname);
       const char* egd_sensor_name(int stype);

DESCRIPTION

       egd_sensor_type()   returns   the   identifier  code  of  the  sensor  type  named  sname.
       egd_sensor_name() is the reverse process:  it  retrieves  the  name  of  the  sensor  type
       identified by stype.

       Depending  on which acquisition devices have been accessed by the library, the sensor type
       identifier for a given name may be different from a previous  program  execution.  However
       once  a  association has been established it is ensured that it will remain the same until
       the process termination.  Additionally,  the  sensor  types  named  "eeg",  "trigger"  and
       "undefined" are always associated respectively to 0, 1 and 2.

RETURN VALUE

       In  case  of  success, egd_sensor_type() returns a non negative value corresponding to the
       identifier of the sensor type called name.  Otherwise it returns -1.

       In case of success, egd_sensor_name() returns the name of the sensor  type  identified  by
       stype. Otherwise, NULL is returned and errno is set accordingly.

ERRORS

       egd_sensor_type() or egd_sensor_name() will fail if:

       EINVAL sname is NULL or refers to an unknown sensor type or if stype is not a known sensor
              type identifier.
