Obsolete since JSAPI 32
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
Converts an integer
jsval to a C integer without any type checking or error handling.
JSVAL_TO_INT converts a specified integer
v, to the corresponding C integer value. If
v is any other type of value, the result is unspecified.
Note that although
jsval is an integer type, it must be treated as opaque. The
jsval encoding of the integer
4, for instance, is not
((jsval) 4) but some other pattern of bits.
