object, has no effect[.](#1.sentence-1)

*Effects*: If *this and p are the same
object, has no effect[.](#3.sentence-1)

Otherwise,
sets both respective pathnames of *this to the respective pathnames of p[.](#3.sentence-2)

p is left in a valid but unspecified state[.](#3.sentence-3)

A valid implementation is swap(p)[.](#3.sentence-4)

*Effects*: Let s be the effective range of source ([[fs.path.req]](fs.path.req "31.12.6.4 Requirements"))
or the range [first, last), with the encoding converted if required ([[fs.path.cvt]](fs.path.cvt "31.12.6.3 Conversions"))[.](#7.sentence-1)

Finds the detected-format of s ([[fs.path.fmt.cvt]](fs.path.fmt.cvt "31.12.6.3.1 Argument format conversions"))
and sets the pathname in that format to s[.](#7.sentence-2)
