SYNOPSIS

6          bson_t *
7          bson_new_from_buffer (uint8_t **buf,
8                                size_t *buf_len,
9                                bson_realloc_func realloc_func,
10                                void *realloc_func_ctx);
11

PARAMETERS

13       • buf:  An  out-pointer  to a buffer containing a serialized BSON docu‐
14         ment, or to NULL.
15
16       • buf_len: An out-pointer to the length of the buffer in bytes.
17
18       • realloc_func: Optional bson_realloc_func for reallocating the buffer.
19
20       • realloc_func_ctx: Optional pointer that will be passed as ctx to  re‐
21         alloc_func.
22

DESCRIPTION

24       Creates a new bson_t using the data provided.
25
26       The  realloc_func, if provided, is called to resize buf if the document
27       is later expanded, for example by a call  to  one  of  the  bson_append
28       functions.
29
30       If  *buf  is initially NULL then it is allocated, using realloc_func or
31       the default allocator, and initialized with an empty BSON document, and
32       *buf_len is set to 5, the size of an empty document.
33

RETURNS

35       A newly-allocated bson_t on success, or NULL.
