PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
getchar - get a byte from a stdin stream
SYNOPSIS
#include <stdio.h>
int getchar(void);
DESCRIPTION
The
getchar() function shall be equivalent to
getc(
stdin).
RETURN VALUE
Refer to
fgetc().
ERRORS

fgetc().
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
If the integer value returned by
getchar() is stored into a variable of type
char and then compared against the integer constant EOF, the comparison may never succeed, because sign-extension of a variable of type
char on widening to integer is implementation-defined.
RATIONALE
None.
