Instead of using the traditional bf(C) functions for manipulating the file
system functions and members defined in the tt(std::filesystem) namespace can
be used. Here is an overvieuw of frequently used bf(C) functions and their
counterparts in the tt(std::filesystem) namespace (tt(fs) is defined as
tt(namespace fs = std::filesystem); tt(name) is either a NTBS
or a tt(std::string), or a tt(fs::path). When used with a traditional bf(C)
functions tt(name) is always an NTBS).

ittq(access)(hi(access)
verb( fs::exists(name) - access()'s F_OK flag.
fs::file_status stat = fs::status(name);
exists(stat); - same
stat.type() != fs::file_type::not_found - same
fs::perms required = fs::perms::owner_read | fs::perms::owner_write;
(stat.permissions() & required) == required - access's R_OK | W_OK flags)
)
ittq(rename)(hi(rename)
For tt(fs::rename src) and tt(dest) can be NTBSs, tt(std::strings) or
tt(fs::path) objects. For the bf(C) tt(rename) function they must be
NTBSs.

ittq(truncate)(hi(truncate)
The argument tt(size) is a tt(std::uintmax_t) value.
