To avoid these situations, memory should be allocated and freed at the same level of abstraction and, ideally, in the same code module. This includes the use of the following memory allocation and deallocation functions described in Section 7.23.3 of the C standard [ISO/IEC 9899:2011]:
| Code Block |
|---|
void *malloc(size_t size); void *calloc(size_t nmemb, size_t size); void *realloc(void *ptr, size_t size); void *aligned_alloc(size_t alignment, size_t size); void free(void *ptr); |
