# gss_display_mech_attr(_:_:_:_:_:)

Returns a human-readable name and description of a mechanism attribute.

## Declaration

```swift
func gss_display_mech_attr(_ minor_status: UnsafeMutablePointer<OM_uint32>, _ mech_attr: gss_const_OID, _ name: gss_buffer_t?, _ short_desc: gss_buffer_t?, _ long_desc: gss_buffer_t?) -> OM_uint32
```

## Parameters

- `minor_status`: A pointer to the secondary status result that provides additional information in case of failure.
- `mech_attr`: The mechanism attribute to examine. See Mechanisms and Authentication in doc://com.apple.gss/documentation/GSS/security-mechanisms for a list of possible values.
- `name`: A buffer the function fills with a human readable version of the mechanism attribute. Release this buffer with a call to doc://com.apple.gss/documentation/GSS/gss_release_buffer(_:_:) when you are done with it.
- `short_desc`: A buffer the function fills with a short description of the mechanism attribute. Release this buffer with a call to doc://com.apple.gss/documentation/GSS/gss_release_buffer(_:_:) when you are done with it.
- `long_desc`: A buffer the function fills with a longer description of the mechanism attribute. Release this buffer with a call to doc://com.apple.gss/documentation/GSS/gss_release_buffer(_:_:) when you are done with it.

## Return Value

Return Value A status code set to GSS_S_COMPLETE on success or GSS_S_BAD_MECH if the desired mechanism is unsupported. See Function Status for a complete enumeration of status outputs.
