GETCHAR(III) − PWB/UNIX 4/7/73
NAME
getchar − read character
SYNOPSIS
getchar( )
DESCRIPTION
Getchar provides the simplest means of reading characters from the standard input for C programs. It returns successive 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 simplest 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 character.
