| #### Audit Trail Descriptor An opaque data type, dce_aud_trail_t, is used to represent an audit trail descriptor. The dce_aud_open( ) function opens an audit trail and returns a trail descriptor; dce_aud_next( ) obtains an audit record from this descriptor; and dce_aud_commit( ) commits an audit record from and to an opened audit trail through this descriptor. The dce_aud_close( ) function disposes of this descriptor. ###
