NAME¶
mongoc_collection_command() - This function shall execute a command on a collection. This is performed lazily and therefore requires calling mongoc_cursor_next() on the resulting cursor structure. The cursor should be freed with mongoc_cursor_destroy() when no longer in use.SYNOPSIS¶
mongoc_cursor_t * mongoc_collection_command (mongoc_collection_t *collection, mongoc_query_flags_t flags, uint32_t skip, uint32_t limit, uint32_t batch_size, const bson_t *command, const bson_t *fields, const mongoc_read_prefs_t *read_prefs) BSON_GNUC_WARN_UNUSED_RESULT;
PARAMETERS¶
- collection
- A mongoc_collection_t
- flags
- A mongoc_query_flags_t
- skip
- A uint32_t with the number of documents to skip or zero.
- limit
- A uint32_t with the max number of documents to return or zero.
- batch_size
- A uint32_t with the number of documents in each batch or zero. Default is 100.
- command
- A bson_t containing the command to execute.
- fields
- A bson_t containing the fields to return or NULL
- read_prefs
- An optional mongoc_read_prefs_t MONGOC_READ_PRIMARY
DESCRIPTION¶
This function shall execute a command on a collection. This is performed lazily and therefore requires calling mongoc_cursor_next(3) on the resulting cursor structure. The cursor should be freed with mongoc_cursor_destroy(3) when no longer in use.RETURNS¶
A lazy mongoc_cursor_t that should be freed with mongoc_cursor_destroy(3)NOTE
Failure to handle the result of this function is a
programming error.
