SYNOPSIS

          typedef struct _bson_mem_vtable_t {
             void *(*malloc) (size_t num_bytes);
             void *(*calloc) (size_t n_members, size_t num_bytes);
             void *(*realloc) (void *mem, size_t num_bytes);
             void (*free) (void *mem);
             void *(*aligned_alloc) (size_t alignment, size_t num_bytes);
             void *padding[3];
          } bson_mem_vtable_t;

          void
          bson_mem_set_vtable (const bson_mem_vtable_t *vtable);

PARAMETERS

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

DESCRIPTION

       This function shall install a new memory allocator to be used by Libbson.

       For   backwards   compatibility,   if   vtable->aligned_alloc   is   not   set,  calls  to
       vtable->aligned_alloc will use vtable->malloc instead.

       WARNING:
          This function MUST be called at the beginning of the process. Failure  to  do  so  will
          result in memory being freed by the wrong allocator.
