30.10 File systems [filesystems]

30.10.34 Filesystem operation functions [fs.op.funcs]

30.10.34.31 Remove all [fs.op.remove_all]

uintmax_t remove_all(const path& p); uintmax_t remove_all(const path& p, error_code& ec) noexcept;

1
#

Effects: Recursively deletes the contents of p if it exists, then deletes file p itself, as if by POSIX remove(). [ Note: A symbolic link is itself removed, rather than the file it resolves to.  — end note ]

2
#

Postconditions: !exists(symlink_­status(p)).

3
#

Returns: The number of files removed. The signature with argument ec returns static_­cast< uintmax_­t>(-1) if an error occurs.

4
#

Throws: As specified in [fs.err.report].
