NAME

bson_array_as_canonical_extended_json − bson_array_as_canonical_extended_json()

SYNOPSIS

char *
bson_array_as_canonical_extended_json (const bson_t *bson, size_t *length);

PARAMETERS

	•		bson: A bson_t.
	•		length: An optional location for the length of the resulting string.

DESCRIPTION

The bson_array_as_canonical_extended_json() encodes bson as a UTF−8 string in the canonical MongoDB Extended JSON format, except the outermost element is encoded as a JSON array, rather than a JSON document.

The caller is responsible for freeing the resulting UTF−8 encoded string by calling bson_free() with the result.

If non−NULL, length will be set to the length of the result in bytes.

RETURNS

If successful, a newly allocated UTF−8 encoded string and length is set.

Upon failure, NULL is returned.

EXAMPLE

#include <bson/bson.h>

int main ()
{
   bson_t bson;
   char *str;

   bson_init (&bson);
   /* BSON array is a normal BSON document with integer values for the keys,
    * starting with 0 and continuing sequentially
    */
   BSON_APPEND_INT32 (&bson, "0", 1);
   BSON_APPEND_UTF8 (&bson, "1", "bar");

   str = bson_array_as_canonical_extended_json (&bson, NULL);
   /* Prints
    * [ { "$numberInt" : 1 }, "bar" ]
    */
   printf ("%s\n", str);
   bson_free (str);

   bson_destroy (&bson);
}
