.desc begin
The &func function takes a pointer to a character string that contains
a pathname, and returns a pointer to a string that is a pathname of the
parent directory of that file. Trailing path separators are not considered
as part of the path.
.np
The &func function may modify the string pointed to by
.arg path
and may return a pointer to static storage that may be overwritten by
a subsequent call to &func..
.np
The &func function is not re-entrant or thread-safe.
.desc end
.*
.return begin
The &func function returns a pointer to a string that is the parent
directory of
.arg path.
If
.arg path
is a null pointer or points to an empty string, a pointer to the string "."
is returned.
