It is intended 53that this example can be used as a template when writing 54a new manual page. 55.Pp 56The 57.Fn example 58function takes two arguments: 59.Fa ptr 60and 61.Fa mode . 62The argument 63.Fa mode 64may have one of the following values: 65.Bl -tag -width EXAMPLE_ONE 66.It Dv EXAMPLE_ONE 67First example of a defined variable. 68.Dv EXAMPLE_ONE 69is described below. 70.It Dv
