WARNING:

          Deprecated since version 1.4.0: This function is deprecated and should not be used in new code.

          Please use mongoc_write_concern_set_journal() in new code.

SYNOPSIS

          void
          mongoc_write_concern_set_fsync (mongoc_write_concern_t *write_concern,
                                          bool fsync_);

PARAMETERS

       • write_concern: A mongoc_write_concern_t.

       • fsync_: A boolean.

DESCRIPTION

       Sets if a fsync must be performed before indicating write success.

       Beginning  in  version  1.9.0, this function can now alter the write concern after it has been used in an
       operation. Previously, using the struct with an operation would mark it  as  "frozen"  and  calling  this
       function would log a warning instead instead of altering the write concern.
