 .Sh DESCRIPTION
 These functions set, unset, fetch, and parse variables from the kernel's
 environment.
 .Pp
 The
 .Fn kern_getenv
 function obtains the current value of the kernel environment variable
 .Fa name
 and returns a pointer to the string value.
 The caller should not modify the string pointed to by the return value.
 The
 .Fn kern_getenv
 function may allocate temporary storage,
 so the
 .Fn freeenv
 function must be called to release any allocated resources when the value
 returned by
 .Fn kern_getenv
 is no longer needed.
 .Pp
 The
 .Fn freeenv
 function is used to release the resources allocated by a previous call to
 .Fn kern_getenv .
 The
 .Fa env
 argument passed to
 .Fn freeenv
 is the pointer returned by the earlier call to
 .Fn kern_getenv .
 Like
 .Xr free 3 ,
 the
 .Fa env
 argument can be
 .Va NULL ,
 in which case no action occurs.
 .Pp
 The
 .Fn kern_setenv
 function inserts or resets the kernel environment variable
 .Fa name
 to
 .Fa value .
 If the variable
 .Fa name
 already exists,
 its value is replaced.
 This function can fail if an internal limit on the number of environment
 variables is exceeded.
 .Pp
 The
 .Fn kern_unsetenv
 function deletes the kernel environment variable
 .Fa name .
 .Pp
 The
 .Fn testenv
 function is used to determine if a kernel environment variable exists.
 It returns a non-zero value if the variable
 .Fa name
 exists and zero if it does not.
 .Pp
 The
 .Fn getenv_int ,
 .Fn getenv_long ,
 .Fn getenv_quad ,
 .Fn getenv_uint ,
 and
 .Fn getenv_ulong
 functions look for a kernel environment variable
 .Fa name
 and parse it as a signed integer,
 long integer,
 signed 64-bit integer,
 unsigned integer,
 or an unsigned long integer,
 respectively.
 These functions fail and return zero if
 .Fa name
 does not exist or if any invalid characters are present in its value.
 On success,
 these function store the parsed value in the integer variable pointed to
 by
 .Fa data .
 If the parsed value overflows the integer type,
 a truncated value is stored in
 .Fa data
 and zero is returned.
 If the value begins with a prefix of
 .Dq 0x
 it is interpreted as hexadecimal.
 If it begins with a prefix of
 .Dq 0
 it is interpreted as octal.
 Otherwise,
 the value is interpreted as decimal.
 The value may contain a single character suffix specifying a unit for
 the value.
 The interpreted value is multiplied by the unit's magnitude before being
 returned.
 The following unit suffixes are supported:
 .Bl -column -offset indent ".Sy Unit" ".Sy Magnitude"
 .It Sy Unit Ta Sy Magnitude
 .It k Ta 2^10
 .It m Ta 2^20
 .It g Ta 2^30
 .It t Ta 2^40
 .El
 .Pp
 The
 .Fn getenv_string
 function stores a copy of the kernel environment variable
 .Fa name
 in the buffer described by
 .Fa data
 and
 .Fa size .
 If the variable does not exist,
 zero is returned.
 If the variable exists,
 up to
 .Fa size - 1
 characters of its value are copied to the buffer pointed to by
 .Fa data
 followed by a null character and a non-zero value is returned.
+.Pp
+The
+.Fn getenv_bool
+function interprets the value of the kernel environment variable
+.Fa name
+as a boolean value by performing a case-insensitive comparison against the
+strings "1",
+"0",
+"true",
+and "false".
+If the environment variable exists and has a valid boolean value, then that
+value will be copied to the variable pointed to by
+.Fa data .
+If the environment variable exists but is not a boolean value, then a warning
+will be printed to the kernel message buffer.
+The
+.Fn getenv_is_true
+and
+.Fn getenv_is_false
+functions are wrappers around
+.Fn getenv_bool
+that simplify testing for a desired boolean value.
 .Sh RETURN VALUES
 The
 .Fn kern_getenv
 function returns a pointer to an environment variable's value on success or
 .Dv NULL
 if the variable does not exist.
 .Pp
 The
 .Fn kern_setenv
 and
 .Fn kern_unsetenv
 functions return zero on success and -1 on failure.
 .Pp
 The
 .Fn testenv
 function returns zero if the specified environment variable does not exist and
 a non-zero value if it does exist.
+.Pp
 The
 .Fn getenv_int ,
 .Fn getenv_long ,
 .Fn getenv_string ,
 .Fn getenv_quad ,
 .Fn getenv_uint ,
+.Fn getenv_ulong ,
 and
-.Fn getenv_ulong
+.Fn getenv_bool
 functions return a non-zero value on success and zero on failure.
+.Pp
+The
+.Fn getenv_is_true
+and
+.Fn getenv_is_false
+functions return
+.Dv true
+if the specified environment variable exists and its value matches the desired
+boolean condition, and
+.Dv false
+otherwise.
