# mongoc\_find\_and\_modify\_opts\_set\_max\_time\_ms(3)

## SYNOPSIS

```
bool
mongoc_find_and_modify_opts_set_max_time_ms (
   mongoc_find_and_modify_opts_t *opts, uint32_t max_time_ms);
```

## PARAMETERS

- •

  **opts**: A *mongoc\_find\_and\_modify\_opts\_t*.

- •

  **max\_time\_ms**: The maximum server-side execution time permitted, in milliseconds, or 0 to specify no maximum time (the default setting).

## DESCRIPTION

Adds a maxTimeMS argument to the builder.

## RETURNS

Returns **true** if it successfully added the option to the builder, otherwise **false** and logs an error.

Note: although **max\_time\_ms** is a uint32\_t, it is possible to set it as a uint64\_t through the options arguments in some cursor returning functions like *mongoc\_collection\_find\_with\_opts()*.

## SETTING MAXTIMEMS
