SYNOPSIS

6          typedef struct _bson_mem_vtable_t {
7             void *(*malloc) (size_t num_bytes);
8             void *(*calloc) (size_t n_members, size_t num_bytes);
9             void *(*realloc) (void *mem, size_t num_bytes);
10             void (*free) (void *mem);
11             void *(*aligned_alloc) (size_t alignment, size_t num_bytes);
12             void *padding[3];
13          } bson_mem_vtable_t;

PARAMETERS

DESCRIPTION

22       This  function shall install a new memory allocator to be used by Libb‐
23       son.
24
25       For backwards compatibility, if vtable->aligned_alloc is not set, calls
26       to vtable->aligned_alloc will use vtable->malloc instead.
27
28       WARNING:
29          This  function MUST be called at the beginning of the process. Fail‐
30          ure to do so will result in memory being freed by the wrong  alloca‐
31          tor.
