 is a String.  Notice that the macros take only the lvalue as their
 argument, to change the value of var in place.
 
+You can also use the macro named StringValueCStr(). This is just
+like StringValuePtr(), but always add nul character at the end of
+the result. If the result contains nul character, this macro causes
+the ArgumentError exception.
+StringValuePtr() doesn't gurantee to exist nul at the end of the
+result, and the result may contain nul.

 In version 1.6 or earlier, STR2CSTR() was used to do the same thing
 but now it is deprecated in version 1.7, because STR2CSTR() has a risk
 of a dangling pointer problem in the to_str() implicit conversion.
