Any comments ?

The same onces as last year.

You should also take a look at locking. You have some locking between
the FS and the functions, but it has race conditions. The locking the
other way does not exist at all.

You also incorrectly use st_mode, but that is minor.

[ECOS] GUI library

Hi,

I'm going to use an open source GUI library to control either 
the Powertip PG240128WRF-ATA-H with Toshiba T6963C and Matrix Touch 5 x 10
AMT8704.
or the 
EDT EW32F40FLW QVGA (320x240) with Epson S1D13305 und TP-9523-5.6 4-wire
analog Touch. 
My target hardware is the LPC-E2294 board from Olimex(www.olimex.com) with
the LPC2294 running ecos.
Unfortunately minigui, my first decision, (minigui.org) needs a lot of
memory to run (recommended are 2MB Ram and 2MB Rom for ecos systems).

Has anyone a suggestion which GUI lib I should use (C/PEG, FLTK,
easygui,...)?

Thanks,

Michael

I'm happy with Allegro on my embedded (mostly) Linux systems. Getting
it to run on eCos shouldn't be too hard -- a week or two I guess. There's
a couple of GUI libraries built on top of Allegro, though I admit I'm using
lowlevel drawing primitives directly to get my UIs painted...

I there really no interest in this?  I've found it useful.
