NAME

       bson_copy_to_excluding_noinit - bson_copy_to_excluding_noinit()

SYNOPSIS

          void
          bson_copy_to_excluding_noinit (const bson_t *src,
                                         bson_t *dst,
                                         const char *first_exclude,
                                         ...) BSON_GNUC_NULL_TERMINATED;

PARAMETERS

       • src: A bson_t.

       • dst: A bson_t.

       • first_exclude: The first field name to exclude.

DESCRIPTION

       The  bson_copy_to_excluding_noinit() function shall copy all fields from src to dst except
       those specified by the variadic, NULL terminated list of keys starting from first_exclude.
       Works  the  same way as bson_copy_to_excluding(), except does not call bson_init() on dst.
       This function should be preferred in new code over bson_copy_to_excluding().

       WARNING:
          This is generally not needed except in very special situations.

EXAMPLE

          #include <bson/bson.h>

          int main ()
          {
             bson_t bson;
             bson_t bson2;
             char *str;

             bson_init (&bson);
             bson_append_int32 (&bson, "a", 1, 1);
             bson_append_int32 (&bson, "b", 1, 2);
             bson_append_int32 (&bson, "c", 1, 2);

             bson_init (&bson2);
             bson_copy_to_excluding_noinit (&bson, &bson2, "b", NULL);

             str = bson_as_json (&bson2, NULL);
             /* Prints
              * { "a" : 1, "c" : 2 }
              */
             printf ("%s\n", str);
             bson_free (str);

             bson_destroy (&bson);
             bson_destroy (&bson2);
          }
