Thread: Negative Return Problem

i Have a Function,whose basic structure is

Code:

 signed char fun()
{
signed char a;
a=-1;
return a;
}

now when i run this code on Coverity tool, i'm getting error as negative return

what can be done to solve this thing?

P.S : please mind that the code i shared is a basic one,
it has lot of dependenies in the program

Are you assigning the return value of your function to an unsigned int, perhaps?
