EGD_SENSOR_TYPE(3)					       EEGDEV library manual						EGD_SENSOR_TYPE(3)

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.   Other-
       wise 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.
