SYNOPSIS mixed deep_copy (mixed arg) DESCRIPTION Create a deep copy of and return it. For arrays and mappings this means that a new array or mapping is created with copies of the original content. Embedded arrays and mappings are truly copied, too. For other values this function is a no-op. If DYNAMIC_COST is defined, every nested mapping or array counts towards the evaluation cost in both size and nesting depth. EXAMPLE mixed *a, *b; a = ({ 1, ({ 21, 22 }) }); b = deep_copy(a); a[0] = -1; a[1][0] = -21; --> a is now ({ -1, ({ -21, 22 }) }) b is still ({ 1, ({ 21, 22 }) }) HISTORY Introduced in LDMud 3.2.6. LDMud 3.2.9 added the dynamic cost to the efun. SEE ALSO copy(E)
