35.Sh LIBRARY 36.\" Note: list of available libraries is available in mdoc(7) 37.Lb libc 38.Sh SYNOPSIS 39.In example.h 40.Ft int 41.Fn example "char *ptr" "int mode" 42.Sh DESCRIPTION 43This is an example library function manual page for the 44.Fn example 45function. 46It is intended that this example can be used as a template 47when writing a new manual page. 48.Pp 49The 50.Fn example 51function takes two arguments: 52.Fa ptr 53and 54.Fa mode . 55The argument 56.Fa mode 57may have one of the following values: 58.Bl -tag -width ".Dv EXAMPLE_ONE" 59.It Dv EXAMPLE_ONE 60First example of a defined variable. 61.Dv EXAMPLE_ONE 62is described below. 63.It Dv EXAMPLE_TWO 64Second example. 65.El 66.Pp 67The above values are defined in 68.In example.h 69as follows: 70.Bd -literal 71#define EXAMPLE_ONE 1 72#define EXAMPLE_TWO 2 73.Ed 74.Sh IMPLEMENTATION NOTES 75The 76.Fn example 77function is not actually implemented. 78.Sh RETURN VALUES 79.Rv -std example 80.Sh ENVIRONMENT 81The 82.Fn example 83library function ignores the 84.Ev EXAMPLE 85environment variable. 86.Sh FILES 87.Bl -tag -width ".Pa /dev/null" -compact 88.It Pa /dev/null 89Example of a file in the 90.Sx FILES 91section. 92.El 93.Sh DIAGNOSTICS 94None. 95.Sh COMPATIBILITY 96The 97.Fn example 98function has no known compatibility issues. 99.Sh ERRORS 100.\" Delete any errno's that are not returned by your 101.\" function or system call and then tailor the 102.\" remaining text as needed. 103The 104.Fn example 105function will fail if: 106.Bl -tag -width Er 107.It Bq Er EPERM 108Operation not
