FUNCRET.GEN
Non-void function doesn't return value
The FUNCRET.GEN checker finds paths in non-void functions that don't have a return statement.
Vulnerability and risk
This situation leaves the returned value uninitialized, so design intent isn't accomplished.
Vulnerable code example
Copy
#include <stdio.h>
int string_len()
{
//...
}
int main()
{
string_len();
return 0;
}Klocwork flags line 5, indicating that the 'int' function has no return. In contrast, the 'main' function with its return statement in line 10 is not flagged.
