NAME

map_delete() - remove a (key, value) pair from a mapping based on the key

SYNOPSIS

void map_delete(mapping m, mixed element)

DESCRIPTION

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].
