__fpurge
FPURGE(3) Linux Programmer's Manual FPURGE(3)
NAME
fpurge, __fpurge - purge a stream
SYNOPSIS
/* unsupported */
#include <stdio.h>
int fpurge(FILE *stream);
/* supported */
#include <stdio.h>
#include <stdio_ext.h>
void __fpurge(FILE *stream);
DESCRIPTION
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.
RETURN VALUE
Upon successful completion fpurge() returns 0. On error, it returns -1 and sets errno appropriately.
ERRORS
EBADF stream is not an open stream.
CONFORMING TO
These functions are nonstandard and not portable. The function fpurge() was introduced in 4.4BSD and is not available under Linux. The
function __fpurge() was introduced in Solaris, and is present in glibc 2.1.95 and later.
NOTES
Usually it is a mistake to want to discard input buffers.
SEE ALSO
fflush(3), setbuf(3), stdio_ext(3)
