comedi_get_max_buffer_size - maximum streaming buffer size
#include <comedilib.h>
int comedi_get_max_buffer_size(comedi_t * device, unsigned int subdevice);
The function comedi_get_max_buffer_size returns the maximum allowable size (in bytes) of the streaming buffer for the subdevice specified by device and subdevice. Changing the maximum buffer size can be accomplished with comedi_set_max_buffer_size or with the comedi_config program, and requires appropriate privileges.
On success, the maximum allowable size (in bytes) of the streaming buffer is returned. On failure, -1 is returned.
