Thanks a lot. That helped an i can now edit the file from vi from
inside gdb itself.
But is there any thing is gdb that prevents 'vi' from loading my
favourite "vimrc"
(vi startup customization file).


I have one more doubt. I have defined a string like

typedef std::basic_string< unsigned short, unsigned_short_traits > utf16string;
utf16string myString; //dont worry about the traits

Is there any thing in gdb that will help me view the string as i view
a ordinary std::string.

As of now i use [x/100s myString.c_str()] or [p /c
*myString.c_str()@100] to examine the
data in the string. Could i use any thing better to view it like an
ordinary string ?
