well, i have a while-loop. and the user enters some chars for some different options.
Right now i'm storing the char in a variable with "charVariable = getchar();" but the user got to press enter before continue. Is there a way to the program will continue after the key is pressed (no <return>).
Thanks.. i tried the select() nad read().. but couldn't make it work as i wanted :)
Then i found this function:
1 2 3 4 5 6 7 8 9 10 11 12 13
struct termios oldt;
struct termios newt;
tcgetattr(STDIN_FILENO, &oldt); /*store old settings */
newt = oldt; /* copy old settings to new settings */
newt.c_lflag &= ~(ICANON | ECHO); /* make one change to old settings in new settings */
tcsetattr(STDIN_FILENO, TCSANOW, &newt); /*apply the new settings immediatly */
ch = getchar(); /* standard getchar call */
tcsetattr(STDIN_FILENO, TCSANOW, &oldt); /*reapply the old settings */
return ch; /*return received char */
