Obtain the select()
sets for this daemon. Daemon's FDs will be added to fd_sets. To get only daemon FDs in fd_sets, call FD_ZERO for each fd_set before calling this function. Size of fd_set is determined by current value of FD_SETSIZE. It's necessary to use MHD_get_timeout() in combination with this function.
This function could be called only for daemon started without MHD_USE_INTERNAL_POLLING_THREAD flag.

Obtain the select()
sets for this daemon. Daemon's FDs will be added to fd_sets. To get only daemon FDs in fd_sets, call FD_ZERO for each fd_set before calling this function. FD_SETSIZE is assumed to be platform's default.
This function should only be called in when MHD is configured to use external select with 'select()' or with 'epoll'. In the latter case, it will only add the single 'epoll()' file descriptor used by MHD to the sets. It's necessary to use MHD_get_timeout() in combination with this function.
This function must be called only for daemon started without MHD_USE_INTERNAL_POLLING_THREAD flag.

Obtain the select()

Passing custom FD_SETSIZE as fd_setsize allow usage of larger/smaller than platform's default fd_sets.

Obtain timeout value for polling function for this daemon. This function set value to amount of milliseconds for which polling function (select()
or poll()
) should at most block, not the timeout value set for connections. It is important to always use this function, even if connection timeout is not set, as in some cases MHD may already have more data to process on next turn (data pending in TLS buffers, connections are already ready with epoll etc.) and returned timeout will be zero.

int MHD_run | ( | struct MHD_Daemon * | daemon | ) |
Run webserver operations (without blocking unless in client callbacks). This method should be called by clients in combination with MHD_get_fdset if the client-controlled select method is used and MHD_get_timeout().
This function is a convenience method, which is useful if the fd_sets from MHD_get_fdset were not directly passed to select()
; with this function, MHD will internally do the appropriate select()
call itself again. While it is always safe to call MHD_run (if MHD_USE_INTERNAL_POLLING_THREAD is not set), you should call MHD_run_from_select if performance is important (as it saves an expensive call to select()
).

Run webserver operations. This method should be called by clients in combination with MHD_get_fdset and MHD_get_timeout() if the client-controlled select method is used.
You can use this function instead of MHD_run if you called select()
on the result from MHD_get_fdset. File descriptors in the sets that are not controlled by MHD will be ignored. Calling this function instead of MHD_run is more efficient as MHD will not have to call select()
again to determine which operations are ready.
This function cannot be used with daemon started with MHD_USE_INTERNAL_POLLING_THREAD flag.
