explain_getchar_or_die - input of characters and report errors
SYNOPSIS
#include <libexplain/getchar.h>
void explain_getchar_or_die(void);
DESCRIPTION
The explain_getchar_or_die function is used to call the getchar(3) system call. On failure an explanation will be printed to stderr,
obtained from explain_getchar(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
int c = explain_getchar_or_die();
Returns:
This function only returns on success. On failure, prints an explanation and exits.

There's a replacement in bash for getchar or get functions of C and C++?Those functions read the next char avaliable in the input stream.
I've tried something like:

Hi,
I would like to read an input from keyboard using getchar. However, if no input (No Carriage return/new line none whatsoever) is given after say, 5 seconds, I would like to skip the getchar and move on. How do I do this in C. I'm using GNU compiler set.
Thanks, (5 Replies)

why would that be? and is there a way to fix that?
printf("3. exit\n");
choice=getchar();

Hi,
What happens to process state when getchar() is called? I wrote a C code in which I call getchar() somewhere down the road. I forgot about that, I started the process, put it in bg and disowned it using "disown". Now, how do I see where that process has gone/how do kill it?
Thanks,
