NAME

6       mongoc_find_and_modify_opts_set_max_time_ms    -   mongoc_find_and_mod‐
7       ify_opts_set_max_time_ms()
8

SYNOPSIS

10          bool
11          mongoc_find_and_modify_opts_set_max_time_ms (
12             mongoc_find_and_modify_opts_t *opts, uint32_t max_time_ms);
13

PARAMETERS

15       · opts: A mongoc_find_and_modify_opts_t.
16
17       · max_time_ms: The maximum server-side  execution  time  permitted,  in
18         milliseconds, or 0 to specify no maximum time (the default setting).
19

DESCRIPTION

21       Adds a maxTimeMS argument to the builder.
22

RETURNS

24       Returns true if it successfully added the option to the builder, other‐
25       wise false and logs an error.
26
27       Note: although max_time_ms is a uint32_t, it is possible to set it as a
28       uint64_t  through  the options arguments in some cursor returning func‐
29       tions like mongoc_collection_find_with_opts().
