NAME

SYNOPSIS

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

18          void
19          bson_mem_set_vtable (const bson_mem_vtable_t *vtable);

PARAMETERS

22       • vtable: A bson_mem_vtable_t with every non-padding field set.

DESCRIPTION

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