NAME

bson_mem_set_vtable − bson_mem_set_vtable()

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.
