Input and Output

s16a_set_output_bits

Description

Set the output resolution of the S16A to 16 or 20 bits.

Syntax

int s16a_set_output_bits(S16aDev *s16a_p, int value);

Arguments
s16a_p	S16A device handle returned from s16a_open
value	Either 16 or 20, indicating the operational mode of the output DAC.

Return

Returns 0 on success or –1 on failure. Fails if s16a_p does not refer to an output channel, or if value is anything but 16 or 20. Sets errno on failure.

s16a_start_buffers

Description

Releases the specified number of buffers to the driver for transfer.

Syntax

int s16a_start_buffers(S16aDev *s16a_p, int bufnum);

Arguments
s16a_p	S16A device handle returned from s16a_open
bufnum	Number of buffers to release to the driver for transfer. An argument of 0 causes the driver
	to perform continuous transfers.

Return

0 on success; –1 on error. If an error occurs, check the errno global variable for the error number.
