Checks to determine if a parity error has occurred since the last time this routine was called and returns 0
if not, 1 if so, and –1 if the routine is not supported for a particular device or an illegal argument was
provided.

int foi_parity_error(S16aDev *s16a_p);

S16A device handle returned from s16a_open

0 if no error; 1 if parity error; –1 if the routine is not supported or if an illegal argument was provided.

The table below shows some of the error codes that may be received from a call to the S16A driver. After
any I/O system call, the errno global variable contains the error code, if any, and the perror system call can
print out a string describing the error code. Refer to your system programming documentation for details
about errno and perror.
