dbm-delete

Arguments: ndbm key &key external-format if-does-not-exist

dbm-delete removes a key from the database specified by ndbm (which should be a value returned by dbm-open). key can be a string or a usb8 array. If key is a string, it will be internally converted to a usb8 array according to the external-format keyword argument (or, if not supplied, the default determined by dbm-open will be used). If the key does not exist in the database, and:

• if-does-not-exist is :error, then an error is signaled.
• if-does-not-exist is nil (the default), then nil is returned

If the key did exist, it is removed and t is returned.

See ndbm.htm for information on the NDBM facility.
