Functions | |
| void | zeromem (void *memory, size_t numBytes) noexcept |
| Fills a block of memory with zeros. | |
| template<typename Type > | |
| void | zerostruct (Type &structure) noexcept |
| Overwrites a structure or object with zeros. | |
| template<typename Type > | |
| void | deleteAndZero (Type &pointer) |
| Delete an object pointer, and sets the pointer to null. | |
| template<typename Type > | |
| Type * | addBytesToPointer (Type *pointer, int bytes) noexcept |
| A handy function which adds a number of bytes to any type of pointer and returns the result. | |
| template<typename Type1 , typename Type2 > | |
| int | getAddressDifference (Type1 *pointer1, Type2 *pointer2) noexcept |
| A handy function which returns the difference between any two pointers, in bytes. | |
| template<class Type > | |
| Type * | createCopyIfNotNull (Type *pointer) |
| If a pointer is non-null, this returns a new copy of the object that it points to, or safely returns nullptr if the pointer is null. | |

| void zeromem | ( | void * | memory, |
| size_t | numBytes | ||
| ) |
Fills a block of memory with zeros.
Referenced by HeapBlock< ObjectClass * >::clear(), and Matrix3D< Type >::Matrix3D().
| void zerostruct | ( | Type & | structure | ) |
Overwrites a structure or object with zeros.
| void deleteAndZero | ( | Type & | pointer | ) |
Delete an object pointer, and sets the pointer to null.
Remember that it's not good c++ practice to use delete directly - always try to use a ScopedPointer or other automatic lifetime-management system rather than resorting to deleting raw pointers!
| Type* addBytesToPointer | ( | Type * | pointer, |
| int | bytes | ||
| ) |
A handy function which adds a number of bytes to any type of pointer and returns the result.
This can be useful to avoid casting pointers to a char* and back when you want to move them by a specific number of bytes,

| int getAddressDifference | ( | Type1 * | pointer1, |
| Type2 * | pointer2 | ||
| ) |
A handy function which returns the difference between any two pointers, in bytes.
The address of the second pointer is subtracted from the first, and the difference in bytes is returned.

| Type* createCopyIfNotNull | ( | Type * | pointer | ) |
If a pointer is non-null, this returns a new copy of the object that it points to, or safely returns nullptr if the pointer is null.
Referenced by ScopedPointer< ListViewport >::createCopy().
