fpurge(3)               Library Functions Manual               fpurge(3)

ИМЯ

       fpurge, __fpurge - purge a stream

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       /* unsupported */
       #include <stdio.h>

       int fpurge(FILE *stream);

       /* supported */
       #include <stdio.h>
       #include <stdio_ext.h>

       void  __fpurge(FILE *stream);

ОПИСАНИЕ

       The function fpurge() clears the buffers of the given stream.
       For output streams this discards any unwritten output.  For input
       streams this discards any input read from the underlying object
       but not yet obtained via getc(3); this includes any text pushed
       back via ungetc(3).  See also fflush(3).

       The function __fpurge() does precisely the same, but without
       returning a value.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       Upon successful completion fpurge() returns 0.  On error, it
       returns -1 and sets errno to indicate the error.

ОШИБКИ

       EBADF  stream is not an open stream.
