NAME
rmdir
—
remove a directory file
SYNOPSIS
#include
<unistd.h>
int
rmdir
(const
char *path);
DESCRIPTION
rmdir
()
removes a directory file whose name is given by path.
The directory must not have any entries other than
‘.
’ and
‘..
’.
There is no
rmdirat
()
function; to remove a directory with a path relative to the directory
associated with a file descriptor use the
unlinkat(2) function with the AT_REMOVEDIR
flag.
RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
