From c431a065ba515d27830f01c852f70940efb3003b Mon Sep 17 00:00:00 2001 From: Lukas Larsson Date: Thu, 2 Jul 2015 11:13:32 +0200 Subject: ose: Remove all code related to the OSE port The OSE port is no longer supported and this commit removed it and any changes related to it. The things that were general improvements have been left in the code. --- lib/ose/doc/src/ose_erl_driver.xml | 111 ------------------------------------- 1 file changed, 111 deletions(-) delete mode 100644 lib/ose/doc/src/ose_erl_driver.xml (limited to 'lib/ose/doc/src/ose_erl_driver.xml') diff --git a/lib/ose/doc/src/ose_erl_driver.xml b/lib/ose/doc/src/ose_erl_driver.xml deleted file mode 100644 index b804c29d2d..0000000000 --- a/lib/ose/doc/src/ose_erl_driver.xml +++ /dev/null @@ -1,111 +0,0 @@ - - - - -

- ose_erl_driver - Linked-in drivers in Enea OSE - -

Writing Linked-in drivers that also work on Enea OSE is very similar for - how you would do it for Unix. The difference from Unix is that - driver_select, ready_input and ready_output all work with signals - instead of file descriptors. This means that the driver_select is - used to specify which type of signal should trigger calls to - ready_input/ready_output. The functions described below are available - to driver programmers on Enea OSE to facilitate this. -

- -
- DATA TYPES - - - union SIGNAL - See the Enea OSE SPI documentation for a description. - SIGSELECT - See the Enea OSE SPI documentation for a description. - ErlDrvEvent - The ErlDrvEvent is a handle to a signal number and id combination. It is passed to driver_select(3). - ErlDrvOseEventId - This is the id used to associate a specific signal to a - certain driver instance. - -
- - - union SIGNAL *erl_drv_ose_get_signal(ErlDrvEvent drv_event) - - -

Fetch the next signal associated with drv_event. - Signals will be returned in the order which they were received and - when no more signals are available NULL will be returned. - Use this function in the ready_input/ready_output callbacks - to get signals.

- - - - ErlDrvEventerl_drv_ose_event_alloc(SIGSELECT signo, ErlDrvOseEventId id, ErlDrvOseEventId (*resolve_signal)(union SIGNAL* sig), void *extra) - - -

Create a new ErlDrvEvent associated with signo, - id and uses the resolve_signal function to extract - the id from a signal with signo. The extra - parameter can be used for additional data. See - - Signals in a Linked-in driver in the OSE User's Guide. -

- - - - voiderl_drv_ose_event_free(ErlDrvEvent drv_event) - - -

Free a ErlDrvEvent. This should always be done in the - stop_select - callback when the event is no longer being used.

- - - - voiderl_drv_ose_event_fetch(ErlDrvEvent drv_event, SIGSELECT *signo, ErlDrvOseEventId *id, void **extra) - - -

Write the signal number, id and any extra data associated with drv_event - into *signo and *id respectively. NULL can be - also passed as signo or id in order to ignore that field. -
