Parasoft检测到错误

Question

我在C中有一个函数，其中包含以下行：

while (src=strstr(src,key)) {
        memmove(src,src+strlen(key),1+strlen(src+strlen(key)));
    }

当我运行parasoft来检查函数时，我从这些行中收到了很多错误：

Not enclosed with brackets assignment was found in 'while' condition expression
LHS operand of '+' operator is 'unsigned long'
LHS operand of '+' operator is 'unsigned long'
LHS operand of '+' operator is 'unsigned long'
RHS operand of '+' operator is 'unsigned long'
RHS operand of '+' operator is 'unsigned long'
RHS operand of '+' operator is 'unsigned long'
Third param to 'memmove' function depends on second: src, key

你知道这些错误的来源吗？

Answer 1

第一条消息是因为该工具怀疑你的意思是：

while ((src = strstr(src, key))) {

为了明确指定作业，有些工具希望你写

DLFileEntryLocalServiceUtil.getFileEntry(long groupId, long folderId, java.lang.String title)
