# ftemp

## Description

Creates a file in the "tmp", "temp" or root directory with random name for reading and writing. The file is deleted after fclose() is used on the file.

## Returns

The temporary file handle. 0 if failed.

## Examples

```c
// Create a temporary file stream
new File:t_handle = ftemp();

// Declare "handle"
new File:handle;

// Declare "g_char"
new 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);

            // Set the file pointer of the temporary file stream to the first byte
            fseek(t_handle, _, seek_begin);
        }
        else
        {
            // Error
            print("Failed to open file \"file1.txt\".");
        }

        // Open "file2.txt" in "write only" mode, and check, if the file is open
        if (handle = fopen("file2.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 "file2.txt"
                fputchar(handle, g_char, false);
            }

            // Close "file2.txt"
            fclose(handle);
        }
        else
        {
            // Error
            print("Failed to open file \"file2.txt\".");
        }
    }
    else
    {
        // Error
        print("Failed to open file \"file.txt\".");
    }

    // Close the temporary file stream
    fclose(t_handle);
}
else
{
    // Error
    print("Failed to create a temporary file stream.");
}
