GETCHAR(III)                  4/7/73                 GETCHAR(III)



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  de-
     scribed under getc(III).

     Generally speaking, getchar should be used only for the sim-
     plest applications; getc is better when there  are  multiple
     input files.

SEE ALSO
     getc(III)

DIAGNOSTICS
     Null character returned on EOF or error.

BUGS
     -1  should  be returned on EOF; null is a legitimate charac-
     ter.
