从文件中读取整数值时,覆盖率检查会产生以下错误

调用函数"fread"taints参数"readval"

//coverity note: Calling function "fread" taints argument "readval".
if(fread(&readval, sizeof(int), 1, fp) < 1) {
    return;
} else {
    //coverity note: Passing tainted variable "readval" to a tainted sink.
    f1(&readval);
}

如何处理这个错误？我需要为'readval'执行什么健全性检查,以确保它没有损坏.
