to ask if a key is pressed

hi guys

I need to run some operation if a key from keyboard is pressed

so I go with

Code:

---

c=getchar();

---

to get it read. yet the user could press a key anytime; so I'd need some if-loop. no plans on how it'd look like though...I suppose something like this below wouldn't work right?

Code:

---


if(getchar()==1){

..

}

---

any hints? thanks

Checking to see whether there is any key requires some OS/Compiler specific coding.

You need to tell us your OS/Compiler if you want specific details.

It's Eclipse based on GNU-C/C++- compiler

OS means operating system.

Standard C doesn't provide that information. You need to use OS specific functions.
