static int MHD_accept_connection | ( | struct MHD_Daemon * | daemon | ) | [static] |
Accept an incoming connection and create the MHD_Connection object for it. This function also enforces policy by way of checking with the accept policy callback.

int MHD_get_timeout | ( | struct MHD_Daemon * | daemon, | |

Obtain timeout value for select for this daemon (only needed if connection timeout is used). The returned value is how long select should at most block, not the timeout value set for connections.
timeout | set to the timeout (in milliseconds) |
