Example Usage:

// Create a temporary file stream
new File:t_handle = ftemp(),
 
	// Declare "handle"
	File:handle,
 
	// Declare "g_char"
	g_char;
 
// Check, if temporary file stream is open
if(t_handle)
{
	// Success
 
	// Open "file.txt" in "read only" mode and check, if the file is open
	if(handle = fopen("file.txt", io_read))
	{
		// Get all the characters from "file.txt"
		while((g_char = fgetchar(handle, 0, false)) != EOF)
		{
			// Write character in lowercase into the temporary file stream
			fputchar(t_handle, tolower(g_char), false);
		}
 
		// Close "file.txt"
		fclose(handle);
 
		// Set the file pointer of the temporary file stream to the first byte
		fseek(t_handle, _, seek_begin);
 
		// Open "file1.txt" in "write only" mode, and check, if the file is open
		if(handle = fopen("file1.txt", io_write))
		{
			// Success
 
			// Get all the characters from the temporary file stream
			while((g_char = fgetchar(t_handle, 0, false)) != EOF)
			{
				// Write character into "file1.txt"
				fputchar(handle, g_char, false);
			}
 
			// Close "file1.txt"
			fclose(handle);

			fseek(t_handle, _, seek_begin);
		}

		{
			// Success
 
			// Get all the characters from the temporary file stream
			while((g_char = fgetchar(t_handle, 0, false)) != EOF)
			{
