BSON_COPY_TO_EXCLUDING_NOINIT(3) libbson BSON_COPY_TO_EXCLUDING_NOINIT(3) SYNOPSIS void bson_copy_to_excluding_noinit (const bson_t *src, bson_t *dst, const char *first_exclude, ...); 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_relaxed_extended_json (&bson2, NULL); /* Prints * { "a" : 1, "c" : 2 } */ printf ("%s\n", str); bson_free (str); bson_destroy (&bson); bson_destroy (&bson2); } AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.2 Apr 12, 2025 BSON_COPY_TO_EXCLUDING_NOINIT(3)
