How to skip getchar in C?
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,

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?

fgetc
FGETC(3) Linux Programmer's Manual FGETC(3)
NAME
fgetc, fgets, getc, getchar, ungetc - input of characters and strings
SYNOPSIS
#include <stdio.h>
int fgetc(FILE *stream);
char *fgets(char *s, int size, FILE *stream);
int getc(FILE *stream);
int getchar(void);
int ungetc(int c, FILE *stream);
DESCRIPTION
fgetc() reads the next character from stream and returns it as an unsigned char cast to an int, or EOF on end of file or error.
getc() is equivalent to fgetc() except that it may be implemented as a macro which evaluates stream more than once.
getchar() is equivalent to getc(stdin).
fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an
EOF or a newline. If a newline is read, it is stored into the buffer. A terminating null byte ('
