SYNOPSIS

#define BSON_APPEND_DOCUMENT_BEGIN(b, key, child) \


   bson_append_document_begin (b, key, (int) strlen (key), child)
bool
bson_append_document_begin (bson_t *bson,


                            const char *key,


                            int key_length,


                            bson_t *child);

PARAMETERS

bson: A bson_t.
key: An ASCII C string containing the name of the field.
key_length: The length of key in bytes, or -1 to determine the length with strlen().
child: An uninitialized bson_t to be initialized as the sub-document.

DESCRIPTION

The bson_append_document_begin() function shall begin appending a sub-document to bson. Use child to add fields to the sub-document. When completed, call bson_append_document_end() to complete the element.

child MUST be an uninitialized bson_t to avoid leaking memory.

RETURNS

Returns true if the operation was applied successfully. The function will fail if bson must grow larger than INT32_MAX.
