NAME

egd_get_numch - Get the number of channels sampled by type

SYNOPSIS

#include <eegdev.h>

int egd_get_numch(const struct eegdev* dev , int stype );

DESCRIPTION

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).

RETURN VALUE

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.

EINVAL

dev is NULL or stype is not valid value.
