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

     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.



SEE ALSO

     getc (III)



DIAGNOSTICS

     Null character returned on EOF or error.



BUGS

     -1  should  be  returned  on  EOF;  null  is  a   legitimate

     character.
