default. To disable them, add the following WARNING_FILTER rule to the
project configuration file.

CodeSonar ships with library models that allow it to recognize functions such as libm acos() that have a parameter whose value should not be less than -1. If one of these functions is called with a value less than -1 in the relevant parameter position, a warning will be issued.
If you have created a custom library model for some function f() in terms of one of these existing models, calls to f() will also be capable of triggering Argument Too Low warnings.
Japanese (ja)
#include <math.h>
double call_asin(double ind){
double a = asin(-1); /* ok */
double b = asin(-2); /* 'Argument Too Low' warning issued here */
double c = asin(ind); /* EVIDENCED ONLY: 'Argument Too Low' warning issued here
* if CodeSonar has evidence that call_asin() is called on a value <-1. */
return a+b+c;
}
The following configuration file parameters affect checks for this warning class.
