When I run the program below the open () statement always returns -1 even if the file exists.
Am I doing something wrong?
#include

int rc;
const char *dbname = "/temp/my_db.sql3";
int MAMain() {
rc = open( dbname, O_WRONLY );
fprintf(stderr, "rc= %-3d %s \n", rc, dbname);
close(rc);
FREEZE;
return 0;
}
Are you running it in the emulator? In that case, the filesystem as exposed to MoSync programs is chrooted in the subdirectory Output/filesystem, of your project directory.
Yes, I am running it in the Mosync Emulator.
I will try it tonight and let you know if that solves my problem but I am not sure it will as
rc = open( dbname, O_WRONLY | O_CREAT);
was also failing.
I'm assuming you use newlib. Which version of MoSync are you using?
I introduced a bug to open() in r1644. If you're using that version or a later one, I'm surprised your program doesn't crash. 
Anyway, after fixing the bug, I tried to run your test program (with one change: const char *dbname = "/my_db.sql3"; // removed "temp/"), and it worked fine, printing "rc= 4 /my_db.sql3".
The fix is in r1652.
Thank you.
I was using 1650.
I will test it tonight.
Thanks,
That fixed the open problem.
Does this work on Nokia Devices.
A Similar Open statement which works on the Emulator seems to fail on a Nokia 5230 Device.
A File name of "test.db" works but something like "/test.db" fails.
Then after I create the file I cannot seem to find it on my device.
