To keep the forums high quality for all users, please take the time to format your posts correctly.
First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)
Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.
Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

MAKEDEV(3) BSD Library Functions Manual MAKEDEV(3)NAME
makedev, major, minor -- device number conversion
SYNOPSIS
#include <sys/types.h>
dev_t
makedev(int major, int minor);
int
major(dev_t dev);
int
minor(dev_t dev);
DESCRIPTION
The makedev() macro allows a unique device number to be generated based on its major and minor number. The major() and minor() macros can be
used to obtain the original numbers from the device number dev.
In previous implementations of FreeBSD all block and character devices were uniquely identified by a pair of major and minor numbers. The
major number referred to a certain device class (e.g. disks, TTYs) while the minor number identified an instance within the device class.
Later versions of FreeBSD automatically generate a unique device number for each character device visible in /dev/. These numbers are not
divided in device classes.
On FreeBSD these macros are only used by utilities that need to exchange numbers with other operating systems that may use different encod-
ings for dev_t, but also applications that present these numbers to the user in a more conventional way.
RETURN VALUES
The major() macro returns a device major number that has a value between 0 and 255. The minor() macro returns a device minor number whose
value can span the complete range of an int.
