comedi_get_timer — timer information (deprecated)
#include <comedilib.h>
int comedi_get_timer( | comedi_t * device, |
| unsigned int subdevice, | |
| double frequency, | |
| unsigned int * trigvar, | |
double * actual_frequency); |
The function comedi_get_timer converts the frequency
frequency
to a number suitable to send to the driver in a comedi_trig
structure. This function remains for compatibility with very
old versions of Comedi, that converted sampling rates to timer
values in the library. This conversion is now done in the kernel,
and every device has the timer type nanosec_timer, indicating
that timer values are simply a time specified in nanoseconds.
