NAME

       mongoc_write_concern_set_wtag - mongoc_write_concern_set_wtag()

SYNOPSIS

          void
          mongoc_write_concern_set_wtag (mongoc_write_concern_t *write_concern,
                                         const char *tag);

PARAMETERS

       • write_concern: A mongoc_write_concern_t.

       • tag: A string containing the write tag.

DESCRIPTION

       Sets  the  write  tag that must be satisfied for the write to indicate success. Write tags
       are preset write concerns configured on your MongoDB  server.  See  mongoc_write_concern_t
       for more information on this setting.

       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.
