bson_append_double - bson_append_double()

#define BSON_APPEND_DOUBLE(b, key, val) \


   bson_append_double (b, key, (int) strlen (key), val)
bool
bson_append_double (bson_t *bson,


                    const char *key,


                    int key_length,


                    double value);


  • 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().
  • value: A double value to append.

The bson_append_double() function shall append a new element to a bson document of type double.

Returns true if the operation was applied successfully. The function will fail if appending value grows bson larger than INT32_MAX.
