NAME

getchar — get a byte from a stdin stream

SYNOPSIS

#include <stdio.h>

int getchar(void);

DESCRIPTION

The getchar() function is equivalent to getc(stdin) .

RETURN VALUE

Refer to fgetc(3) .

ERRORS

Refer to fgetc(3) .

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-dependent.

FUTURE DIRECTIONS

None.
