## SYNOPSIS

```
mongoc_client_t *
mongoc_client_pool_try_pop (mongoc_client_pool_t *pool);

**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* if one is immediately available, otherwise **NULL**.

## THREAD SAFETY

This function is safe to call from multiple threads.
