map_delete - remove a (key, value) pair from a mapping based on the key void map_delete( mapping m, mixed element ); map_delete removes the (key, value) from the mapping m that has key equal to element. For example, given:
mapping names;

names = ([]);
names["truilkan"] = "john";
names["wayfarer"] = "erik";
names["jacques"] = "dwayne";
Then:
map_delete(names,"truilkan");
causes the mapping 'names' to be equal to:
(["wayfarer" : "erik", "jacques" : "dwayne"])
keys(names) will not contain "truilkan" after map_delete(names,"truilkan") is called [unless ("truilkan", *) is subsequently added back to the mapping]. See also: allocate_mapping Tim Hollebeek Beek@ZorkMUD, Lima Bean, IdeaExchange, and elsewhere
