+.Sh DESCRIPTION
+The
+.Fn REQUIRE ,
+.Fn ENSURE ,
+.Fn INSIST ,
+and
+.Fn INVARIANT
+macros evaluate a boolean expression, and if it is false, they invoke the
+current assertion failure callback. The default callback will print a message
+to
+.Li stderr
+describing the failure, and then cause the program to dump core.
+If the
+.Dq Fn _ERR
+variant of the assertion is used, the callback will include
+.Fn strerror "errno"
+in its message.
+.Pp
+Each assertion type has an associated
+.Li CHECK
+macro. If this macro's value is
+.Dq 0
+when
+.Dq "<isc/assertions.h>"
+is included, then assertions of that type will not be checked. E.g.
+.Pp
+.Dl #define CHECK_ENSURE 0
+.Pp
+will disable checking of
+.Fn ENSURE
+and
+.Fn ENSURE_ERR .
+The macros
+.Li CHECK_ALL
+and
+.Li CHECK_NONE
+may also be used, respectively specifying that either all or none of the
+assertion types should be checked.
+.Pp
+.Fn set_assertion_failure_callback
+specifies the function to call when an assertion fails.
+.Pp
+When an
+.Fn assertion_failure_callback
+is called, the
+.Fa filename
+and
+.Fa line
+arguments specify the filename and line number of the failing assertion.
+The
+.Fa type
+is one of:
+.Bd -literal -offset indent
+assert_require
+assert_ensure
+assert_insist
+assert_invariant
+.Ed
+.Pp
+and may be used by the callback to determine the type of the failing
+assertion.
+.Fa condition
+is the literal text of the assertion that failed.
+.Fa print_errno
+will be non-zero if the callback should print
+.Fa strerror "errno"
+as part of its output.
+.Pp
+.Fn assertion_type_to_text
+returns a textual representation of
+.Fa type .
+For example,
+.Fn assertion_type_to_text "assert_require"
+returns the string
+.Dq REQUIRE .
