Thread: (!_kbhit()) problem in Dev-C++

I was looking over some code put together by Harpreet Singh Juneja and tried to compile it to see what happens. I get these two errors:

90 d:\portsp~1\hsport.cpp
implicit declaration of function `int _kbhit(...)'

102 d:\portsp~1\hsport.cpp
implicit declaration of function `int _getch(...)'

I am thinking that the problem is this was done in VC++ and I am using Dev-C++.

here is the part with the problem:

Code:

	
			if (strlen(buffer) > 2)					/* we have a wait specification */
				{	
					hsport.token(&buffer[1],&token_ptr);
					if (token_ptr != NULL)				/* if pattern specified */
					{	
						sscanf(token_ptr,"%x",&match_byte);
						printf("Waiting for byte %4.4x.  Hit any key to terminate\n",match_byte);
						hsport.rdport();
						while (!_kbhit())
						{
							save_byte = hsport.getbyte();
							hsport.rdport();
							if (hsport.getbyte() == match_byte)
							{
								printf("Pattern %4.4x found, hit any key.\n",hsport.getbyte());
								hsport.setbyte(save_byte);
								break;
							}
							hsport.setbyte(save_byte);
						}
						_getch();	/* clears the port */
					}
				}

so how should it be fixed?

Perhaps the library that comes with Dev-C++ has kbhit and getch without the underscores. Did you #include <conio> or <conio.h> or <conio.c>? There are a lot of platforms where at least one of those works.

You need to include <conio.h> to use _kbhit(). I use _kbhit at the end of my console programs.

In Dev-C++?

here are the results:
<conio> ; no such...
<conio.c> ; 31 errors
<conio.h> ; same two errors as original
delete underscore ; more of same type of errors showed up, deleted all underscores. one error left. 91 d:\portsp~1\hsport.cpp
implicit declaration of function `int kbhit(...)'

Code:

while (!kbhit()

I found this in a search: http://cboard.cprogramming.com/showthread.php?t=16550

What version of Dev-C++ do you have? Maybe upgrading to 4.9.9.2 will help if you don't have the latest.

is there another way to do the same thing? (without the errors)

By the way, I can't the search on this forum. it times out every time.
