Synopsis:
    #include <dos.h>
    unsigned _dos_commit( int handle );

Description:
    The _dos_commit function uses system call 0x68 to flush to disk the DOS
    buffers associated with the file indicated by handle.  It also forces an
    update on the corresponding disk directory and the file allocation
    table.

Returns:
    The _dos_commit function returns zero if successful.  Otherwise, it
    returns a DOS error code and sets  errno to  EBADF indicating an invalid
    file handle.

Example:
    #include <stdio.h>
    #include <dos.h>
    #include <fcntl.h>

    void main()
      {
        int handle;

        if( _dos_open( "file", O_RDONLY, handle ) != 0 ) {
            printf( "Unable to open file\n" );
        } else {
            if( _dos_commit( handle ) == 0 ) {
                printf( "Commit succeeded.\n" );
            }
            _dos_close( handle );
        }
      }

    produces the following:

    Commit succeeded.
