Hi Al,
This is what I am doing.
------------------------------------------------
>FileHand out;
>Err errOpen;
>Err errClose;
>out = FileOpen(0, "MyApp.xml", 0, 0 ,
fileModeReadWrite | fileModeDontOverwrite, &errOpen);
>errClose = FileClose(out);
------------------------------------------------
This code works fine the first time. If the same code
is called again the second time, I am getting this
error.
----------------------------------------------
"MyApp just read from memory location 0x0003BEEE,
which is in an unallocated chunk of memory."
-----------------------------------------------
When I did a backtrace in PRC-Debugger,
---------------------------------------------
Program received signal SIGTRAP, Trace/breakpoint
trap.
0x10c3ad72 in PrvValidateFileDescriptor ()

----------------------------------------------
When I did a dir using Palm Debugger for the XML file,
------------------------------------------------
name ID total data
--------------------------------------------------
TikTok.xml 000402DF 0.084 Kb 0.000 Kb
TikTok.xml 000402DF 0.084 Kb 0.000 Kb
------------------------------------------------------Total:
2
--------------------------------------------------
Why is it showing two entries for the same file?
The error is coming when the FileClose() is called the
second time.
Thanks,
Rudra
