Changing the I/O Buffer Size
The following example opens a file named SAMPLE.TXT for unbuffered I/O, and
then enables buffered I/O with an internal 16K buffer using the mmioSetBuffer
if ((hFile = mmioOpen("SAMPLE.TXT", NULL, MMIO_READ)) != NULL)
// File opened successfully; request an I/O buffer.
if (mmioSetBuffer(hFile, NULL, 16384L, 0))
// Buffer cannot be allocated.
// Buffer allocated successfully.
// File cannot be opened.
