NAME
getchar - read character
SYNOPSIS
getchar( )
DESCRIPTION
Getchar provides the simplest means of reading characters
from the standard input for C programs. It returns succes-
sive characters until end-of-file, when it returns ``\0''.
Associated with this routine is an external variable called
fin, which is a structure containing a buffer such as
described under getc (III).
Generally speaking, getchar should be used only for the sim-
plest applications; getc is better when there are multiple
input files.

DIAGNOSTICS
Null character returned on EOF or error.
BUGS
-1 should be returned on EOF; null is a legitimate charac-
ter.
