RE: [ECOS] Block devices vs Character devices.

[<felixwong at i-technologies dot cc>]

You are right.  I missed out my modification for subroutine "dev_fo_lseek" in "devfs.cxx".
The modification should be:
//    *pos = 0;			<< old line.
    fp->f_offset = *pos;		<< my updated line.
    
These are the minimum modifications (together with mods in "dev_fo_read" & "dev_fo_write") 
for my application.

As my harddisk device require partition storage size larger than 2GB.
Another change would be in "ecos\packages\isoinfra\current\include\sys\types.h"

typedef unsigned long long off_t;		(originally "long" instead of "long long")

This update is only required for >2GB storage devices.

FW.

You mean when will it include your patch? It just missed today's update, so
it will probably be in just over two weeks when I return from vacation and
can do another update.

Something should probably be done about dev_fo_lseek too.
