Deprecated functions Function: comedi_dio_bitfield -- read/write multiple digital channels Retval: int Param: comedi_t * device Param: unsigned int subdevice Param: unsigned int write_mask Param: unsigned int * bits Status: deprecated Description: This function is deprecated. Use comedi_dio_bitfield2 instead. It is equivalent to using comedi_dio_bitfield2 with base_channel set to 0. Function: comedi_get_buffer_offset -- streaming buffer status (deprecated) Status: deprecated Description: This function is deprecated. Use comedi_get_buffer_read_offset instead. It has the same functionality as comedi_get_buffer_read_offset. Function: comedi_get_timer -- timer information (deprecated) Retval: int Param: comedi_t * device Param: unsigned int subdevice Param: double frequency Param: unsigned int * trigvar Param: double * actual_frequency Status: deprecated Description: 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. Function: comedi_sv_init -- slowly-varying inputs Retval: int Param: comedi_sv_t * sv Param: comedi_t * device Param: unsigned int subdevice Param: unsigned int channel Status: deprecated Description: The function comedi_sv_init initializes the slow varying Comedi structure pointed to by sv to use the device device, the analog input subdevice subdevice, and the channel channel. The slow varying Comedi structure is used by comedi_sv_measure to accurately measure an analog input by averaging over many samples. The default number of samples is 100. Returns: This function returns 0 on success, -1 on error. Function: comedi_sv_measure -- slowly-varying inputs Retval: int Param: comedi_sv_t * sv Param: double * data Status: deprecated Description: The function comedi_sv_measure uses the slowly varying Comedi structure pointed to by sv to measure a slowly varying signal. If successful, the result (in physical units) is stored in the location pointed to by data, and the number of samples is returned. On error, -1 is returned. Function: comedi_sv_update -- slowly-varying inputs Retval: int Param: comedi_sv_t * sv Status: deprecated Description: The function comedi_sv_update updates internal parameters of the slowly varying Comedi structure pointed to by sv. Function: comedi_timed_1chan -- streaming input (deprecated) Retval: int Param: comedi_t * device Param: unsigned int subdevice Param: unsigned int channel Param: unsigned int range Param: unsigned int aref Param: double frequency Param: unsigned int num_samples Param: double * data Status: deprecated Description: Not documented. Function: comedi_trigger -- perform streaming input/output (deprecated) Retval: int Param: comedi_t * device Param: comedi_trig * trig Status: deprecated Description: The function comedi_trigger instructs Comedi to perform the command specified by the trigger structure pointed to by trig. The return value depends on the particular trigger being issued. If there is an error, -1 is returned.
