flushall

Usage

   #include <stdio.h>
   int flushall(void);

Description

   flushall flushes the I/O buffers for all open streams. Output buffers are
   written to their associated files and input buffers are cleared. All
   streams remain open after a call to flushall. Any read operation reads
   new data into the buffers.

Example 

   #include <stdio.h>

   #include <stdlib.h>

   int main()
   {
       int totalflushed;
       totalflushed = flushall();
       return EXIT_SUCCESS;
   }

Return Value

   flushall returns the number of open streams.
