Casting Using the Built-In Types

TotalView provides a number of predefined types. These types are preceded by a $. You can use these built-in types anywhere you can use the ones defined in your programming language. These types are also useful in debugging executables with no debugging symbol table information. The following table describes the 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. The complex types contain a real part and an imaginary part, which are both of type real.
$complex_8	Fortran	complex*8	A real*4-precision floating-point complex number. The complex*8 types contain a real part and an imaginary part, which are both of type real*4.
$complex_16	Fortran	complex*16	A real*8-precision floating-point complex number. The complex*16 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; often long 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 real*4 or real*8, 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_t data 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
