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

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.
