getchar() -- STDIO Function (libc)

Read character from standard input
#include <stdio.h>
int getchar()

getchar() reads  a character from the standard input.   It is equivalent to
getc(stdin).

Example

The following  example gets one  or more characters from  the keyboard, and
echoes them on the screen.

#include <stdio.h>

main()
{
    int foo;
    while ((foo = getchar()) != EOF)
        putchar(foo);
}

Diagnostics

getchar() returns EOF at end of file or on read error.

If you  wish to receive  characters from the  keyboard immediately, without
waiting for the enter key, see the example in the entry for pipe().
