Hi,

Why not use busybox syslogd, which has precisely this feature. Busybox
is at www.busybox.net. Get the latest stable version, 0.60.5, edit the
Config.h file and make sure you enable BB_FEATURE_IPC_SYSLOG. Start
syslogd with the -C switch and all messages are held in a circular
buffer. Its only 16KB by default, but you can patch the code to make it
bigger if necessary. You read the log using the command logread. I use
it a lot in my embedded projects.

Hope this helps,
Chris Simmonds
