remove_all
C imitation of
std::filesystem::remove_all()from C++17.
SYNOPSIS
#include <remove_all.h>
int remove_all(const char * const p);
DESCRIPTION
Deletes the contents of p (if it is a directory)
and the contents of all its subdirectories, recursively,
then deletes p itself as if by repeatedly applying the POSIX remove.
Symlinks are not followed (symlink is removed, not its target).
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.
ERRORS
The errors that occur are those for unlink(2) and rmdir(2).
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
| Interface | Attribute | Value |
|---|---|---|
| rename_all() | Thread safety | MT-Safe |
BUGS
Infelicities in the protocol underlying NFS can cause the unexpected disappearance of files which are still being used.
SEE ALSO
remove(2),
unlink(2),
rmdir(2),
NOTES
The C++ remove_all returns the number of deleted files,
we instead copy the return value schema of POSIX (and remove(3)).
Currently only works under POSIX.
