SYNOPSIS

int mapping_contains(mixed &data1, ..., &dataN, map, key)

DESCRIPTION

If the mapping contains the key map, the corresponding values are assigned to the data arguments, which massed be passed by reference, and 1 is returned. If key is not in map, 0 is returned and the data args are left unchanged. It is possible to use this function for a 0-value mapping, in which case it has the same effect as member.
