jsval
constants that represent the JavaScript values true
and false
.
Syntax
JSVAL_TRUE JSVAL_FALSE
Description
JSVAL_TRUE
and JSVAL_FALSE
are jsval
constants that represent the JavaScript boolean values, true
and false
. They are equivalent to
and BOOLEAN_TO_JSVAL
(true)BOOLEAN_TO_JSVAL(false)
, respectively.
Take care not to confuse the jsval
constants JSVAL_TRUE
and JSVAL_FALSE
with the bool
constants true
and false
. jsval
values must not be used as C true/false values; there is no guarantee that the C bit-pattern of any particular jsval
is zero or nonzero.
