<filesystem> operators

  • Grein

The operators perform a lexical comparison of two paths as strings. Use the equivalent function to determine whether two paths (for example a relative path and an absolute path) refer to the same file or directory on disk.

For more information, see File System Navigation (C++).

operator==

bool operator==(const path& left, const path& right) noexcept;

The function returns left.native() == right.native().

operator!=

bool operator!=(const path& left, const path& right) noexcept;

The function returns !(left == right).

operator<

bool operator<(const path& left, const path& right) noexcept;

The function returns left.native() < right.native().

operator<=

bool operator<=(const path& left, const path& right) noexcept;

The function returns !(right < left).

operator>

bool operator>(const path& left, const path& right) noexcept;

The function returns right < left.

operator>=

bool operator>=(const path& left, const path& right) noexcept;

The function returns !(left < right).

operator/

path operator/(const path& left, const path& right);

The function executes:

basic_string<Elem, Traits> str;
path ans = left;
return (ans /= right);

operator<<

template <class Elem, class Traits>
basic_ostream<Elem, Traits>& operator<<(basic_ostream<Elem, Traits>& os, const path& pval);

The function returns os << pval.string<Elem, Traits>().

operator>>

template <class Elem, class Traits>
basic_istream<Elem, Traits>& operator<<(basic_istream<Elem, Traits>& is, const path& pval);

The function executes:

basic_string<Elem, Traits> str;
is>> str;
pval = str;
return (is);
