SYNOPSIS

9          mongoc_cursor_t *
10          mongoc_database_command (mongoc_database_t *database,
11                                   mongoc_query_flags_t flags,
12                                   uint32_t skip,
13                                   uint32_t limit,
14                                   uint32_t batch_size,
15                                   const bson_t *command,
16                                   const bson_t *fields,
17                                   const mongoc_read_prefs_t *read_prefs)
18             BSON_GNUC_WARN_UNUSED_RESULT;

20       This  function  is  superseded  by mongoc_database_command_with_opts(),
21       mongoc_database_read_command_with_opts(),    mongoc_database_write_com‐
22       mand_with_opts(), and mongoc_database_read_write_command_with_opts().
23

DESCRIPTION

25       This function creates a cursor which will execute the command when mon‐
26       goc_cursor_next is called on it. The database's read  preference,  read
27       concern,  and  write  concern  are not applied to the command, and mon‐
28       goc_cursor_next will not check the server response for a write  concern
29       error or write concern timeout.
30
31       This function is not considered a retryable read operation.
32

PARAMETERS

34database: A mongoc_database_t.
35
36flags: A mongoc_query_flags_t.
37
38skip: The number of documents to skip on the server.
39
40limit: The maximum number of documents to return from the cursor.
41
42batch_size:  Attempt  to  batch  results from the server in groups of
43         batch_size documents.
44
45command: A bson_t containing the command.
46
47fields: An optional bson_t containing the fields to return. NULL  for
48         all fields.
49
50read_prefs:  An  optional mongoc_read_prefs_t. Otherwise, the command
51         uses mode MONGOC_READ_PRIMARY.
52

RETURNS

54       This function returns a newly allocated mongoc_cursor_t that should  be
55       freed  with mongoc_cursor_destroy() when no longer in use. The returned
56       mongoc_cursor_t is never NULL, even on error. The user must  call  mon‐
57       goc_cursor_next()  on  the returned mongoc_cursor_t to execute the ini‐
58       tial command.
59
60       Cursor errors can be checked with mongoc_cursor_error_document. It  al‐
61       ways  fills  out  the bson_error_t if an error occurred, and optionally
62       includes a server reply document if the error occurred server-side.
63
64       WARNING:
65          Failure to handle the result of this function is a  programming  er‐
66          ror.
