Parameters
| Parameter | Type | Description |

The connection, for which the context has to be returned, or NULL |
Return Value

void * |

Description
The function mg_get_thread_pointer() returns the user defined pointer associated with the thread.
This pointer is set as return value of the mg_init_thread callback (see struct mg_callbacks).
The conn parameter can be NULL - in this case, the user defined pointer is taken from the thread local storage.
For callbacks executed by server worker threads, conn can be the connection handle - in this case,
the user defined pointer is taken from the connection handle.
In both cases, the result will be the same pointer. Reading the pointer from the connection handle might be
faster on some systems.
