# gss_verify_mic(_:_:_:_:_:)

Returns an indication of whether the integrity of a message is intact, given its MIC token.

```
func gss_verify_mic(_ minor_status: UnsafeMutablePointer<OM_uint32>, _ context_handle: gss_ctx_id_t, _ message_buffer: gss_buffer_t, _ token_buffer: gss_buffer_t, _ qop_state: UnsafeMutablePointer<gss_qop_t>?) -> OM_uint32
```

## Parameters

`minor_status`

A pointer to the secondary status result that provides additional information in case of failure.

`context_handle`

The context used to send the message.

`message_buffer`

A buffer holding the message to verify.

`token_buffer`

A buffer holding the token representing the cryptographic signature the protects the message.

`qop_state`

A pointer the function uses to return the quality of protection setting. See Quality of Protection Constants in [Object Identifiers](/documentation/GSS/object-identifiers) for valid values. Pass `NULL` to ignore this output.

## Return Value

A status code set to [`GSS_S_COMPLETE`](/documentation/GSS/GSS_S_COMPLETE) if the message is valid, or another value that indicates the reason for failure. See [Function Status](/documentation/GSS/function-status) for a complete enumeration of status outputs.
