GETCHAR(3P)             POSIX Programmer's Manual            GETCHAR(3P)

ПРЕДИСЛОВИЕ

       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.

НАЗВАНИЕ

       getchar — get a byte from a stdin stream

СИНТАКСИС

       #include <stdio.h>

       int getchar(void);

ОПИСАНИЕ

       The functionality described on this reference page is aligned
       with the ISO C standard. Any conflict between the requirements
       described here and the ISO C standard is unintentional. This
       volume of POSIX.1‐2017 defers to the ISO C standard.

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

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       Refer to fgetc(3p).

ОШИБКИ

       None.

ИСПОЛЬЗОВАНИЕ В ПРИЛОЖЕНИЯХ

       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.

ОБЪЯСНЕНИЕ

       None.
