} 上面这段代码的意思是:我想分配一个不定长的数组,于是我有一个结构体,其中有两个成员,一个是length,代表数组的长度,一个是contents,代码数组的内容。后面代码里的 this_length(长度是10)代表是我想分配的数据的长度。(这看上去是不是像一个C++的类?)这种玩法英文叫:Flexible Array,中文翻译叫:柔性数组。 我...
c zero length array 零长度数组 structlen;data[0]; }; 在阅读一些开源代码时,比如linux kernel,会发现上面这种用法,这种叫做零长度数组。有什么作用呢?简单来说为了开发便利,顺便节省空间。 使用限制 只能放在结构体结尾,也就是一个结构体只能有一个零长度数组。 使用场景 比如我们有一个变长的数据块,如何保存...
没有元素的阵列也称为「长度为零的阵列」(Zero-length Array)。含有长度为零的阵列的变数并不会具有 Nothing 值。 msdn.microsoft.com|基于5个网页 2. 零长度阵列 您可以将阵列的其中一个维度宣告为 -1,宣告「零长度阵列」(Zero-length Array)。含有长度为零的阵列的变数并不会具有 Noth… ...
错误信息 "error: array subscript 1 is outside the bounds of an interior zero-length array" 指出,在尝试访问一个内部长度为零的数组的索引1时,发生了越界错误。这意味着你试图访问的数组(或类似数组的数据结构)实际上是一个空数组,因此没有任何元素可供访问。 分析导致该错误的常见原因 数组初始化错误:在...
You're using a zero-length array as an attribute argument, most commonly as a params parameter. The false positives are due to a breaking change in the C# compiler. Consider using a newer analyzer that contains the fix for the false positive warnings. Upgrade to Microsoft.CodeAnalysis.NetAnaly...
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making...
Incorrect Structure Definition: Ifdtv_slotinfocontains a zero-length array (which is often used in C/C++ for flexible array members), make sure you’re allocating enough space for the structure plus any elements you intend to use. The structure might look something like this: ...

We are dealing with an array section, not an element. For a subscripts triplet, "the sequence is empty if the first subscript is greater than the second". For an array section "Each subscript ... shall be within the bounds for its dimension unless the sequence...
This was not a problem when I only had one array DDXAlloc, it worked as the data was read into the array at the "END" of the heap and did not get overwritten, but when I put in DISLIN it must have written to the heap and DDXALLOC must have interfered. I tried to solve the ...
