NAME

       mongoc_read_concern_set_level - mongoc_read_concern_set_level()

SYNOPSIS

          bool
          mongoc_read_concern_set_level (mongoc_read_concern_t *read_concern,
                                         const char *level);

PARAMETERS

read_concern: A mongoc_read_concern_t.

       • level: The readConcern level to use.

DESCRIPTION

       Sets the read concern level. See mongoc_read_concern_t for details.

       Beginning in version 1.9.0, this function can now alter the read 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  return  false  instead of altering the read
       concern.

RETURNS

       Returns true if the read concern level was set, or false otherwise.
