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 as ctx to realloc_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.
RETURNS
A newly-allocated bson_t on success, or NULL.
