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.
