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.
