bson_new_from_buffer()¶
Synopsis¶
bson_t *
bson_new_from_buffer (uint8_t **buf,
size_t *buf_len,
bson_realloc_func realloc_func,
void *realloc_func_ctx);
Parameters¶
buf
: An out-pointer to a buffer containing a serialized BSON document, or to NULL.buf_len
: An out-pointer to the length of the buffer in bytes.realloc_func
: Optional bson_realloc_func for reallocating the buffer.realloc_func_ctx
: Optional pointer that will be passed asctx
torealloc_func
.
Description¶
Creates a new bson_t using the data provided.
The realloc_func
, if provided, is called to resize buf
if the document is later expanded, for example by a call to one of the bson_append
functions.
If *buf
is initially NULL then it is allocated, using realloc_func
or the default allocator, and initialized with an empty BSON document, and *buf_len
is set to 5, the size of an empty document.
