+### `httplib_pthread_cond_wait( cv, mutex );`
+
+### Parameters
+
+| Parameter | Type | Description |
+| :--- | :--- | :--- |
+|**`cv`**|`pthread_cond_t`|The condition to wait for|
+|**`mutex`**|`pthread_mutex_t *`|The mutex to release when the condition is met|
+
+### Return Value
+
+| Type | Description |
+| :--- | :--- |
+|`int`|Integer value with a success or error code of the function call|
+
+### Description
+
+The platform independent function `httplib_pthread_cond_wait()` is used to wait for a specific condition to be met. After the condition is met, the specified mutex is unlocked. If the function succeeds, the value **0** is returned, otherwise the return value is an error code. On systems which support it, the functionality is implemented as a direct call to `pthread_cond_wait()`. Otherwise an OS dependent alternative function is called.
