SYNOPSIS
void mongoc_client_set_read_prefs (mongoc_client_t *client, const mongoc_read_prefs_t *read_prefs); Sets the default read preferences to use with future operations upon client. The global default is to read from the replica set primary. It is a programming error to call this function on a client from a mongoc_client_pool_t. For pooled clients, set the read preferences with the MongoDB URI instead. Please see the MongoDB website for a description of Read Preferences.
PARAMETERS
• client: A mongoc_client_t. • read_prefs: A mongoc_read_prefs_t.
