Reallocation of memory block with checking.
Reallocates memory block with checking of successful reallocation. The size of the memory block pointed to by the ptr parameter is changed to the size bytes, expanding or reducing the amount of memory available in the block.
The function may move the memory block to a new location, in which case the new location is returned. The content of the memory block is preserved up to the lesser of the new and old sizes, even if the block is moved. If the new size is larger, the value of the newly allocated portion is indeterminate.
In case that ptr is NULL, the function behaves exactly as malloc, assigning a new block of size bytes and returning a pointer to the beginning of it.
In case that the size is 0, the memory previously allocated in ptr is deallocated as if a call to free was made, and a NULL pointer is returned.
- Parameters
-
| [in] | ptr | Pointer to a memory block previously allocated |
| [in] | size | New size for the memory block, in bytes. |
- Returns
- same as ISO C realloc()
