CodeSonar ships with library models that allow it to functions such as libm sqrt() that compute a square root. If one of these functions is called with a negative value in the input parameter 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 sqrt on Negative Value warnings.
English (en)
#include <math.h>
double mysqrt(double d){
return sqrt(d) /* two 'sqrt on Negative Value' warnings reported here:
* - one with path starting in call_sqrtneg_one()
* - one with path starting in call_sqrtneg_ten()
*/
+ sqrt(d+5); /* one 'sqrt on Negative Value' warning reported here,
* with path starting in call_sqrtneg_ten()
*/
}
/* -1.0 is negative, -1.0 + 5 is not */
double call_sqrtneg_one(void){ return mysqrt(-1.0); }
/* -10.0 is negative, -10.0 + 5 is also negative */
double call_sqrtneg_ten(void){ return mysqrt(-10.0); }
