Hi there,
I have recently suffered the lack of the function changing cursor position to the specified coordinates (QNX 4.25)
Finally I've found term_cur() function which uses one of the global terminal strucutres (don't remember the name now). Anyway it does not work as I was expecting... Maybe it's because I use standard printf function to print the text... these two functionalities are the only one I need: moving cursor somewhere and printing the string.
Do you folks know how to solve this problem? Maybe other functions? |

| IIRC, term_cur was supplied in a supplemental library with QNX4 to provide compatibility with the old QNX2 term style functions. You are correct, if you expect it to work you need to use term_printf to print and you generally can't mix and match functions. term_printf takes row and column arguments as a starting position. IIRC, you need to do a term_load to initialize the library before using any of them. |

thanks guys, of course I do use term_load() function but never used #define N_ATTR with the term_printf function. Anyway I will try to check it. the other reason may be that I am referring to the wrong library as a compilation parameter (without one library i couldn't compile it at all, although i included <sys/qnxterm.h> )
second issue: i suppose gets() also won't work properly, is there any other terminal function to read the string (with spaces) from the console?
and at last: do you know how to run qnx 4.25 from windows platform? E.g using virtual machine? And I am not thinking of QNX Neutrino... just old 4.25 |

Actually if you run your console in ANSI-mode you can use ANSI-Style to move the cursor.
It was something like:
In Shell do (for ANSIable Shell):
Code:
export TERM=ansi
stty protocol=1 term=$TERM
For xy coordinates use:
Code:
void gotoxy (int x, int y) {
char c[7];
c[0] = 0x9b;
c[1] = 0x30+y/10;
c[2] = 0x30+y%10;
c[3] = 0x3b;
c[4] = 0x30+x/10;
c[5] = 0x30+x%10;
c[6] = 0x48;
printf(c);
return;
}

thx a lot. the library was: termlib3r
and it was okay, but I did have to switch between terminal functions and others standard input/output. So I used term_load and term_restore functions to enable/disable terminal couple times in the code.
Anyway big thanks, application works really well... and fast 
cheers,
dc. |
