Hi again,

One more thing,

In the command you suggested there is this :- file_to_convert . May I know what is this for?


Thanks.

Hi Smiling Dragon.

Thanks for the reply. I am actually using

cat bla.txt| sed 's/(char|int|str)/\@/g' | sed 's/[\w]/t/g' | sed 's/[\*\,\;\(\)\{\}]/s/g' | sed 's/\@/d/g'>blabla.txt

And i get this:-

addstrscsoutsetsjsmaxsets
charcs
charsoutsets
intsjs

However, the function name "addstr" and other characters could not be converted to other characters.

One thing I do not get you is :-
sed 's/(char|int|str)/\@/g' | sed 's/[\w]/t/g'
The above is to replace char, int and str with "@" right? And what is "w" means in this case?

In your previous reply, you mentioned that by taking the full words to tokenise and exchange them for something 'safe' that subsequent replacements won't hit.What possible way can these int,char,str be recognized? For example; charc could be recognized as "char" and "c"
separately.

One more thing, assume that the previous example; could I just delete the function name off just right before "(" so that the tokenization works much simpler way? Can it be done using SED? If so, how is that possible.

Hope to hear from you soon!Thanks.

curs_addstr(3X) 														   curs_addstr(3X)

NAME
addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr, mvwaddnstr - add a string of characters to a curses window and advance cursor SYNOPSIS
#include <curses.h> int addstr(const char *str); int addnstr(const char *str, int n); int waddstr(WINDOW *win, const char *str); int waddnstr(WINDOW *win, const char *str, int n); int mvaddstr(int y, int x, const char *str); int mvaddnstr(int y, int x, const char *str, int n); int mvwaddstr(WINDOW *win, int y, int x, const char *str); int mvwaddnstr(WINDOW *win, int y, int x, const char *str, int n); DESCRIPTION
These routines write the characters of the (null-terminated) character string str on the given window. It is similar to calling waddch once for each character in the string. The four routines with n as the last argument write at most n characters. If n is -1, then the entire string will be added, up to the maximum number of characters that will fit on the line, or until a terminating null is reached. RETURN VALUE
All routines return the integer ERR upon failure and OK on success (the SVr4 manuals specify only "an integer value other than ERR") upon successful completion. NOTES
Note that all of these routines except waddstr and waddnstr may be macros. PORTABILITY
All these entry points are described in the XSI Curses standard, Issue 4. The XSI errors EILSEQ and EOVERFLOW, associated with extended- level conformance, are not yet detected. SEE ALSO
curses(3X), curs_addch(3X). curs_addstr(3X)
