NAME

       mongoc_client_pool_pop - mongoc_client_pool_pop()

SYNOPSIS

          mongoc_client_t *
          mongoc_client_pool_pop (mongoc_client_pool_t *pool)
             BSON_GNUC_WARN_UNUSED_RESULT;

       Retrieve  a  mongoc_client_t  from  the  client  pool,  or create one. The total number of
       clients that can be created from this pool is limited by  the  URI  option  "maxPoolSize",
       default   100.  If  this  number  of  clients  has  been  created  and  all  are  in  use,
       mongoc_client_pool_pop   blocks   until   another   thread   returns   a    client    with
       mongoc_client_pool_push().  If  the  "waitQueueTimeoutMS"  URI option was specified with a
       positive value, then mongoc_client_pool_pop will return NULL when the timeout expires.

       The returned mongoc_client_t must be returned to the pool with mongoc_client_pool_push().

PARAMETERS

       • pool: A mongoc_client_pool_t.
