DESCRIPTION

15       The getchar() function shall be equivalent to getc(stdin).

APPLICATION USAGE

29       If the integer value returned by getchar() is stored into a variable of
30       type char and then compared against the integer constant EOF, the  com‐
31       parison may never succeed, because sign-extension of a variable of type
32       char on widening to integer is implementation-defined.
33

RATIONALE

35       None.
