Casting to Another Type

Cast a variable into an array by adding an array specifier to the Type declaration. For example, adding [3] to a variable declared as an int changes it into an array of three ints.

Press Enter to cast the variable:

Because the debugger doesn’t know that this is a pointer to an array of ints, to display the array, change its type to $string *[10].

Then click the down arrow to display your array of 10 strings.

Table 4: TotalView Built-in Types
Type String	Language	Size	Description
$address	C	void*	Void pointer (address).
$char	C	char	Character.
$character	Fortran	character	Character.
$code	C	architecture-dependent	Machine instructions.The size used is the number of bytes required to hold the shortest instruction for your computer.
$complex	Fortran	complex	Single-precision floating-point complex number.Thecomplex types contain a real part and an imaginary part, which are both of type real.
$complex_8	Fortran	complex*8	Areal4-precision floating-point complex number.Thecomplex8 types contain a real part and an imaginary part, which are both of type real*4.
$complex_16	Fortran	complex*16	Areal8-precision floating-point complex number.Thecomplex16 types contain a real part and an imaginary part, which are both of type real*8.
$double	C	double	Double-precision floating-point number.
$double_precision	Fortran	double precision	Double-precision floating-point number.
$extended	C	architecture-dependent;oftenlong double	Extended-precision floating-point number. Extended-precision numbers must be supported by the target architecture. In addition, the format of extended floating point numbers varies depending on where it's stored. For example, the x86 register has a special 10-byte format, which is different than the in-memory format. Consult your vendor’s architecture documentation for more information.
$float	C	float	Single-precision floating-point number.
$int	C	int	Integer.
$integer	Fortran	integer	Integer.
$integer_1	Fortran	integer*1	One-byte integer.
$integer_2	Fortran	integer*2	Two-byte integer.
$integer_4	Fortran	integer*4	Four-byte integer.
$integer_8	Fortran	integer*8	Eight-byte integer.
$logical	Fortran	logical	Logical.
$logical_1	Fortran	logical*1	One-byte logical.
$logical_2	Fortran	logical*2	Two-byte logical.
$logical_4	Fortran	logical*4	Four-byte logical.
$logical_8	Fortran	logical*8	Eight-byte logical.
$long	C	long	Long integer.
$long_long	C	long long	Long long integer.
$real	Fortran	real	Single-precision floating-point number.When using a value such as real, be careful that the actual data type used by your computer is not real4 or real8, since different results can occur.
$real_4	Fortran	real*4	Four-byte floating-point number.
$real_8	Fortran	real*8	Eight-byte floating-point number.
$real_16	Fortran	real*16	Sixteen-byte floating-point number.
$short	C	short	Short integer.
$string	C	char	Array of characters.
$void	C	long	Area of memory.
$wchar	C	platform-specific	Platform-specific wide character used by wchar_tdata types
$wchar_s16	C	16 bits	Wide character whose storage is signed 16 bits (not currently used by any platform)
$wchar_u16	C	16 bits	Wide character whose storage is unsigned 16 bits
$wchar_s32	C	32 bits	Wide character whose storage is signed 32 bits
$wchar_u32	C	32 bits	Wide character whose storage is unsigned 32 bits
$wstring	C	platform-specific	Platform-specific string composed of $wchar characters
$wstring_s16	C	16 bits	String composed of $wchar_s16 characters (not currently used by any platform)
$wstring_u16	C	16 bits	String composed of $wchar_u16 characters
$wstring_s32	C	32 bits	String composed of $wchar_s32 characters
$wstring_u32	C	32 bits	String composed of $wchar_u32 characters
