+### `httplib_pthread_key_delete( key );`
+
+### Parameters
+
+| Parameter | Type | Description |
+| :--- | :--- | :--- |
+|**`key`**|`pthread_key_t`|The key to delete|
+
+### Return Value
+
+| Type | Description |
+| :--- | :--- |
+|`int`|Integer value with the result of the function|
+
+### Description
+
+The platform independent function `httplib_pthread_key_delete()` is used to delete a previously allocated key to thread specific data memory. The function returns **0** when succesful or an error code if something went wrong. On systems which support it, the functionality is implemented as a direct call to `pthread_key_delete()`. Otherwise own code is used with equivalent functionality.
