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).
