NAME

7

SYNOPSIS

9          bool
10          mongoc_client_command_simple (mongoc_client_t *client,
11                                        const char *db_name,
12                                        const bson_t *command,
13                                        const mongoc_read_prefs_t *read_prefs,
14                                        bson_t *reply,
15                                        bson_error_t *error);
16
17       This  is  a simplified interface to mongoc_client_command(). It returns
18       the first document from the result cursor into reply. The client's read
19       preference, read concern, and write concern are not applied to the com‐
20       mand.
21
22       WARNING:
23          reply is always set, and should be released with bson_destroy().
24
25       This function is not considered a retryable read operation.
26

PARAMETERS

28       · client: A mongoc_client_t.
29

31
32       · command: A bson_t containing the command specification.
33
34       · read_prefs: An optional mongoc_read_prefs_t. Otherwise,  the  command
35         uses mode MONGOC_READ_PRIMARY.
36
37       · reply: A location for the resulting document.
38
39       · error: An optional location for a bson_error_t or NULL.

46       invalid arguments or a server or network error.

49       error or write concern timeout.
