    NAME

    fflush - flush a stream
     
    

    SYNOPSIS

    #include <stdio.h>

    int fflush(FILE *stream);  

    DESCRIPTION

    The function fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. The open status of the stream is unaffected.

    If the stream argument is NULL, fflush() flushes all open output streams.

    For a non-locking counterpart, see unlocked_stdio(3).  

    RETURN VALUE

    Upon successful completion 0 is returned. Otherwise, EOF is returned and the global variable errno is set to indicate the error.  

    ERRORS

    EBADF
    Stream is not an open stream, or is not open for writing.

    The function fflush() may also fail and set errno for any of the errors specified for the routine write(2).  

    CONFORMING TO

    C89, C99.  

    NOTES

    Note that fflush() only flushes the user space buffers provided by the C library. To ensure that the data is physically stored on disk the kernel buffers must be flushed too, for example, with sync(2) or fsync(2).  

    SEE ALSO

    fsync(2), sync(2), write(2), fclose(3), fopen(3), setbuf(3), unlocked_stdio(3)
