bson_append_maxkey - bson_append_maxkey()

#define BSON_APPEND_MAXKEY(b, key) \


   bson_append_maxkey (b, key, (int) strlen (key))
bool
bson_append_maxkey (bson_t *bson, const char *key, int key_length);


  • 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().

The bson_append_maxkey() function shall append an element of type BSON_TYPE_MAXKEY to a bson document. This is primarily used in queries and unlikely to be used when storing a document to MongoDB.

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