+/***
+The fn(tmpnam) function generates a unique file name that can be used as a
+temporary file. A new file name is generated every time the function is called
+up to macro(TMP_MAX) times.
+
+If arg(s) is macro(NULL), the temporary name is stored in a static internal
+buffer. This buffer may be overwritten by additional calls to fn(tmpnam).
+
+If arg(s) is not macro(NULL), it should point to a type(char) array of at least
+macro(L_tmpnam) characters. The temporary name will be copied to this array.
