fflush

Description

Flush a file to disk (ensure all writes are complete). Actually just calls flength as that has to force a flush to be accurate.

Returns

true - The function was executed successfully.

false - The function failed to execute. (Invalid file handle)

Examples

// Open "file.txt" in "append only" mode
new File:handle = fopen("file.txt", io_append);

// Check, if the file is opened
if (handle)
{
    // Success

    // Append "This is a text.\r\n"
    fwrite(handle, "This is a text.\r\n");

    fflush(handle);

    // Close the file
    fclose(handle);
}
else
{
    // Error
    print("The file \"file.txt\" does not exists, or can't be opened.");
}
