String Constants
String constants are enclosed in double quotes (") and are automatically assigned
the type string by the D compiler. You can define string constants
of any length, limited only by the amount of memory DTrace is
permitted to consume on your system. The terminating null byte (\0) is
added automatically by the D compiler to any string constants that you
declare. The size of a string constant object is the number of
bytes associated with the string plus one additional byte for the terminating
null byte.
A string constant may not contain a literal newline character. To create
strings containing newlines, use the \n escape sequence instead of a literal
newline. String constants may also contain any of the special character escape
sequences defined for character constants in Table 2-5.
