# gss_verify(_:_:_:_:_:)

Returns a flag that indicates the integrity of a message’s digital signature.

## Declaration

```swift
func gss_verify(_ minor_status: UnsafeMutablePointer<OM_uint32>, _ context_handle: gss_ctx_id_t, _ message_buffer: gss_buffer_t, _ token_buffer: gss_buffer_t, _ qop_state: UnsafeMutablePointer<Int32>) -> 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 doc://com.apple.gss/documentation/GSS/object-identifiers for valid values. Pass NULL to ignore this output.

## Return Value

Return Value A status code set to GSS_S_COMPLETE on success. See Status Codes for a complete enumeration of status outputs.
