std::experimental::filesystem::perms – std::experimental::filesystem::perms Synopsis Defined in header <experimental/filesystem> enum class perms; (filesystem TS) This type represents file access permissions. perms satisfies the requirements of BitmaskType (which means the bitwise operators operator&, operator|, operator^, operator~, operator&=, operator|=, and operator^= are defined for this type) Access permissions model POSIX_permission_bits, and any individual file permissions (as reported by…

std::experimental::filesystem::permissions – std::experimental::filesystem::permissions Synopsis Defined in header<experimental / filesystem> void permissions(const path &p, perms prms); (filesystem TS) void permissions(const path &p, perms prms, error_code &ec); Changes access permissions of the file to which p resolves, as if by POSIX fchmodat. Symlinks are followed if prms::resolve_symlinks is set. The effects depend on prms as follows: *…

std::experimental::filesystem::path::root_directory – std::experimental::filesystem::path::root_directory Synopsis path root_directory() const; (filesystem TS) Returns the root directory of the path. If the path does not include root name, returns path(). Parameters (none) Return value The root directory of the path. Exceptions (none) Example // Run this code #include <iostream> #include <experimental/filesystem> namespace fs = std::experimental::filesystem; int main() { fs::path…

std::experimental::filesystem::path::replace_filename – std::experimental::filesystem::path::replace_filename Synopsis path& replace_filename( const path& replacement ); (filesystem TS) Replaces a single filename component with replacement. Equivalent to the following: remove_filename(); operator/=(replacement); The behavior is undefined if the path has no filename component (has_filename returns false). Parameters (none) Return value *this Exceptions (none) Example // Run this code #include <iostream> #include <experimental/filesystem>…

std::experimental::filesystem::path::replace_extension – std::experimental::filesystem::path::replace_extension Synopsis path &replace_extension(const path &replacement = path()); (1)(filesystem TS) Replaces the extension with replacement or removes it when the default value of replacement is used. Firstly, if this path has an extension(), it is removed. Then, a dot character is appended if replacement is not empty or does not begin with a…

std::experimental::filesystem::path::remove_filename – std::experimental::filesystem::path::remove_filename Synopsis path& remove_filename() (1) (filesystem TS) Removes a single filename component. The behavior is undefined if the path has no filename component (has_filename returns false). Parameters (none) Return value *this Exceptions (none) Example // Run this code #include <iostream> #include <experimental/filesystem> namespace fs = std::experimental::filesystem; int main() { std::cout << fs::path("/foo").remove_filename() <<…

std::experimental::filesystem::path::relative_path – std::experimental::filesystem::path::relative_path Synopsis path relative_path() const; (filesystem TS) Returns path relative to root_path. If *this is an empty path, returns an empty path. Parameters (none) Return value Path relative to the root_path.

std::experimental::filesystem::path::parent_path – std::experimental::filesystem::path::parent_path Synopsis path parent_path() const; (filesystem TS) Returns the path to the parent directory. Returns empty path if empty() or there’s only a single element in the path (begin() == –end(). The resulting path is constructed by appending all elements in a range [begin(), –end()) to an empty path. Parameters (none) Return value…
