Accepts input character without pressing [ENTER]

hi all ,
i am new to this forum ..
but i have a question and i cant find the answer anywhere on the internet ..
i need to get an user input and accepts the input without the need of the user pressing enter ...
below is my code ... i am running this code under solaris 9

if(nRetVal >= 0)
{
while(DbObj.getNextTrans()>=0) //getNextRec if getNextRec more than 0 (record exist)
DbObj.printTransDetails(); //call function printTransDetails to output record
char breakRec;
cout << "Press [m] to Return to Main Menu" << endl;
breakRec = getchar();
if(breakRec == 'm') //check if user input 'm'
{
return -1;
}

the problem with this code is that after the user enters m .. he needs to press enter or else the system wouldnt
accept m as the input ..
anyone ? please help ...
thanks in advance

does it have to be "m" ?
why not just have it be "Press any key to return to the main menu" and use system("pause") ?
or, use getchar() and have it be "Press [ENTER] to return to the main menu"

Hey! The problem is that getchar() requires the user to press enter. In windows, for example, there's a function like bioskey which allows you to detect the key code without enter. Try finding a function like that for solaris

there's kbhit(), but that only tells you if a key has been pressed, not which one was pressed
