PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding
8       Linux  manual page for details of Linux behavior), or the interface may
9       not be implemented on Linux.

NAME

12       getchar - get a byte from a stdin stream
13

SYNOPSIS

15       #include <stdio.h>
16
17       int getchar(void);
18
19

DESCRIPTION

21       The getchar() function shall be equivalent to getc(stdin).
22

RETURN VALUE

24       Refer to fgetc().
25

ERRORS

27       Refer to fgetc().
28
29       The following sections are informative.
30

EXAMPLES

32       None.
33

APPLICATION USAGE

35       If the integer value returned by getchar() is stored into a variable of
36       type  char and then compared against the integer constant EOF, the com‐
37       parison may never succeed, because sign-extension of a variable of type
38       char on widening to integer is implementation-defined.
39

RATIONALE

41       None.
42

FUTURE DIRECTIONS

44       None.
