SYNOPSIS¶

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

PARAMETERS¶

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);
}
