NAME

6       mongoc_client_pool_pop - mongoc_client_pool_pop()

SYNOPSIS

9          mongoc_client_t *
10          mongoc_client_pool_pop (mongoc_client_pool_t *pool);
11
12       Retrieve a mongoc_client_t from the client pool, or create one. The to‐
13       tal number of clients that can be created from this pool is limited  by
14       the  URI  option  "maxPoolSize", default 100. If this number of clients
15       has been created and all are in use, mongoc_client_pool_pop blocks  un‐
16       til  another thread returns a client with mongoc_client_pool_push(). If
17       the "waitQueueTimeoutMS" URI  option  was  specified  with  a  positive
18       value,  then  mongoc_client_pool_pop  will return NULL when the timeout
19       expires.
20
21       The returned mongoc_client_t must be returned to  the  pool  with  mon‐
22       goc_client_pool_push().
