-.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 .
