| void* malloc( std::size_t size ); |
||
Allocates size bytes of uninitialized storage.
If allocation succeeds, returns a pointer to the lowest (first) byte in the allocated memory block that is suitably aligned for any object type.
If size is zero, the behavior is implementation defined (null pointer may be returned, or some non-null pointer may be returned that may not be used to access storage)

Parameters
| size | - | number of bytes to allocate |
Return value
Pointer to the beginning of newly allocated memory or null pointer if error has occurred. The pointer must be deallocated with free().
Notes
This function does not call constructors or initialize memory in any way. Thus preferred method of memory allocation is new expression.
