# Dir.mktmpdir creates a temporary directory.

# The directory is created with 0700 permission. Application should not change
# the permission to make the temporary directory accessible from other users.
#
# The prefix and suffix of the name of the directory is specified by the
# optional first argument, *prefix_suffix*.
# * If it is not specified or nil, "d" is used as the prefix and no suffix is
# used.
# * If it is a string, it is used as the prefix and no suffix is used.
# * If it is an array, first element is used as the prefix and second element
# is used as a suffix.
