Define Documentation

#define cpp_lengthof (   base,
  variable 
)    (cpp_sizeof(base, variable) / cpp_sizeof(base, variable[0]))

Gets the length of an array variable within a class.

Parameters:
base The class the variable is in.
variable The array variable to get the size of.
Returns:
the length of the array

Definition at line 438 of file stdafx.h.

#define cpp_sizeof (   base,
  variable 
)    (sizeof(((base*)8)->variable))

Gets the size of a variable within a class.

Parameters:
base The class the variable is in.
variable The variable to get the size of.
Returns:
the size of the variable

Definition at line 430 of file stdafx.h.

#define endof (   x  )     (&x[lengthof(x)])

Get the end element of an fixed size array.

Parameters:
x The pointer to the first element of the array
Returns:
The pointer past to the last element of the array

#define lastof (   x  )     (&x[lengthof(x) - 1])

Get the last element of an fixed size array.

Parameters:
x The pointer to the first element of the array
Returns:
The pointer to the last element of the array

Definition at line 417 of file stdafx.h.

#define lengthof (   x  )     (sizeof(x) / sizeof(x[0]))

Return the length of an fixed size array.

Unlike sizeof this function returns the number of elements of the given type.

Parameters:
x The pointer to the first element of the array
Returns:
The number of elements

Definition at line 401 of file stdafx.h.

#define MAX_UVALUE (   type  )     ((type)~(type)0)

The largest value that can be entered in a variable.

Parameters:
type the type of the variable

Function Documentation

static void free ( const void *  ptr  )  [inline, static]

Version of the standard free that accepts const pointers.

Parameters:
ptr The data to free.
