= flushall =
== Syntax ==
:{{int flushall()}}
== Arguments ==
:none
== Return ==
:Returns the number of files flushed.
== Description ==
:Writes all remaining data in the writing buffer of all opened files and streams.
:The main use of this function is security; ensuring the data is stored in the file in order to protect against crashes. Use this function if your file format allows processing of the partial file.
== Example ==
<code>
int FMI_FILE;
if (FMI_FILE = fopen("d:\\FM_image0.fmi", "wb")) {
  // Write out the src pixels as raw data
  for (z = 0; z < Z; ++z) {
    for (y = 0; y < Y; ++y) {
      for (x = 0; x < X; ++x) {
        fputc(src(x, y, z), IMG_FILE);
      }
    }
    flushall(); // ensure complete channel is stored before next channel is written.
  }
}
else
  ErrorOk("Cannot write image file\nDrive is either full or write-protected!");

if (fclose(IMG_FILE))
  ErrorOk("Cannot close image file!");
