MONGOC_CLIENT_POOL_POP(3) libmongoc MONGOC_CLIENT_POOL_POP(3) SYNOPSIS mongoc_client_t * mongoc_client_pool_pop (mongoc_client_pool_t *pool); 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 cre- ated and all are in use, mongoc_client_pool_pop blocks until another thread returns a client with mongoc_client_pool_push(). If the "waitQueueTime- outMS" URI option was specified with a positive value, then mon- goc_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(). NOTE: Return a checked out mongoc_client_t to the pool with mongoc_client_pool_push() quickly to encourage reuse of clients among threads. PARAMETERS * pool: A mongoc_client_pool_t. RETURNS A mongoc_client_t. THREAD SAFETY This function is safe to call from multiple threads. AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.8 Aug 27, 2026 MONGOC_CLIENT_POOL_POP(3)
