foi_parity_error

Description

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.

Syntax

int foi_parity_error(S16aDev *s16a_p);

Arguments

s16a_p

S16A device handle returned from s16a_open

Return

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

Error Conditions

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.

Error Code	Failing Driver Call	Error Condition


ENXIO	open	The S16A attach failed. The device is not present.
EEXIST	open	The S16A is already opened with an exclusive lock.
