The Hummingbird interface


This section describes the basic Hummingbird calls. All routines return a positive integer or zero if the operation succeeds; a negative return value is an error code.

Missing from this API are commands such as ls and df. We have seen no need for such commands for a caching web proxy. For example, the existence of a file can be determined with read_file().
