Description
BSON_MEM_SET_VTABLE
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.
