In transferring C progams written in Borland C++ to Linux v6.0 I find that getch(), curon(), and curoff() functions are not recognized by gcc. Do these functions actually exist in gcc? If so, what is the header file name? If not, any suggestions on how to add them to gcc?

I have tried inline assembly which didn't work for the following reason....I get an error msg when the command 'int x010' executes. I have tried changing the argument to $10,$32,$16. The error msg when one stepping through the program in gdb is always:
'program received signal SIGSEGV, segmentation fault'
and the program terminates. Any suggestions?

getch is in curses.h (try "man getch")

I can't seem to find much reference to the curon and curoff functions. Tell me what these functions do. Maybe even provide some documentation on them if you have it.

Thanks for your reply, Justin. Here is the info you requested.
curoff() turns the cursor off
curon() turns the cursor on
getch() gets a character from the keyboard without echo and returns immediately without waiting for a \r. It differs from getchar() in these two respects; no echo, no wait for \r
Use of these functions in Borland C++ requires conio.h which does not exist in gcc. Use of these functions is described in the manual provide in the C starter kit from Sams Publishing 'Teach Yourself C in 21 Days', authors Aiken & Jones.
I tried man getch; got no such entry msg. I'm using RedHat LINUX v6.0. I do not find curses.h in the /usr/include/ directory.

curses.h is included in the ncurses library. I'm not sure about the other two functions, but you might look at curs_set.

Here is a good look at curses.h.

Good Luck,

Thanks Justin,
I will try ncurses and let you know if I have success!

For info, functions are provided by libraries (e.g. the aforementioned ncurses library) and not by the compiler itself.
