Enables or disables command-by-command verification of switching functions.

DWORD swiSetVerify ( SWIHD swihd
unsigned verify)

swihd Handle returned by swiOpenSwitch.

verify Specifies whether to enable or disable verification. A non-zero value enables verification, and zero (0) disables verification.

• SUCCESS
• CTAERR_DRIVER_ERROR
  The underlying driver retrieved an unrecognized error. Call swiGetLastError to retrieve the MVIP device error code.
• CTAERR_INVALID_HANDLE
  swihd is not a valid switch handle.

• None.

This function enables or disables command-by-command verification of switching functions. If verification of commands is enabled, the driver verifies low-level switch I/O operations and returns the error CTAERR_DRIVER_ERROR if the driver detects an internal switching error.

Refer to Section 7.2, Verifying Switching Operations for more information.

If CTAERR_DRIVER_ERROR is returned, call swiGetLastError to retrieve the MVIP device error code.
