Prototype

int _flushall(void);

Description

Flushes all streams.

_flushall clears all buffers associated with open input streams and writes all buffers associated with open output streams to their respective files. Any read operation following _flushall reads new data into the buffers from the input files. Streams stay open after _flushall executes.

Return Value

_flushall returns an integer the number of open input and output streams.

Example

 #include <stdio.h>
 int main(void)
 {
    FILE *stream;
    /* create a file */
    stream = fopen("DUMMY.FIL", "w");
    /* flush all open streams */
    printf("%d streams were flushed.\n", flushall());
    /* close the file */
    fclose(stream);
    return 0;
 }
