s16a_done

Description

Returns the cumulative count of completed buffer transfers.

Syntax

int s16a_done_count(S16aDev *s16a_p);

Arguments

s16a_p

S16A device handle returned from s16a_open.

Return

The number of completed buffer transfers. Completed buffers are numbered consecutively starting with 0 when the S16A is opened. (Thus, the allocated buffer number is the transferred buffer number modulo the number of allocated buffers.)

s16a_get_dac_control_reg

Description

Get current state of the output DAC control register. To check for an error, clear the errno global variable before calling this function, then check it for non-zero after the function returns.

Syntax

u_int s16a_get_dac_control_reg(S16aDev *s16a_p);

Arguments

s16a_p

S16A device handle returned from s16a_open

Return

Integer containing current state of the DAC Control register. The global variable errno is set on error.
