.Pq Dv PATH_MAX + 1
including the null byte,
.Fn getwd
fails and returns a null pointer.
.Sh RETURN VALUES
Upon successful completion, a pointer to the string containing the absolute
pathname of the current working directory is returned.

returns a null pointer and the contents of the array pointed to by
.Fa path_name
are undefined.
