Entry: INT_FITS_IN_JSVAL (Macro)
Summary: Determines if a specified value is a valid JS integer.
Syntax:
INT_FITS_IN_JSVAL(i)
Description:
Determines if a specified C integer value, i, lies within the minimum and maximum ranges allowed for a jsval integer. If the value is within range, it can become a valid JS integer, and INT_FITS_IN_JSVAL is true. Otherwise INT_FITS_IN_JSVAL is false.
Example:
The following code snippet illustrates how a JavaScript variable, MyItem, is conditionally tested in an if statement to see if it is a legal integer value.
if (INT_FITS_IN_JSVAL(MyItem)) {
. . .
}
else
JS_ReportError(MyContext, "Integer out of range: %s",
MyItem);
