- terminology - What does it mean by buffer? - Stack Overflow
Here, the buffer array is used to store the data read by read (2) until it's written; then the buffer is re-used There are more complicated buffer schemes used, for example a circular buffer, where some finite number of buffers are used, one after the next; once the buffers are all full, the index "wraps around" so that the first one is re-used
- What is the difference between buffer and cache memory in Linux?
Buffers are associated with a specific block device, and cover caching of filesystem metadata as well as tracking in-flight pages The cache only contains parked file data That is, the buffers remember what's in directories, what file permissions are, and keep track of what memory is being written from or read to for a particular block device The cache only contains the contents of the files
- What is a buffer overflow and how do I cause one?
A buffer overflow is basically when a crafted section (or buffer) of memory is written outside of its intended bounds If an attacker can manage to make this happen from outside of a program it can cause security problems as it could potentially allow them to manipulate arbitrary memory locations, although many modern operating systems protect against the worst cases of this While both
- How to determine the size of an allocated C buffer? [duplicate]
Since buffer is a pointer (not an array), the sizeof operator returns the size of a pointer, not the size of the buffer it points to There is no standard way to determine this size, so you have to do the bookkeeping yourself (i e remember how much you allocated )
- What is the Python buffer type for? - Stack Overflow
The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string This isn't very useful for short strings like this, but it can be necessary when using large amounts of data
- keepass - How to convert Buffer lt;ArrayBufferLike gt; to ArrayBuffer in . . .
1 In your code you use KeePassFileBuffer buffer directly, which may cause a potential mismatch in content, as this is the internal ArrayBuffer, which may contain additional data In the way you use it that is not very likely, but better ensure to extract the relevant portion This how you can convert the Buffer<ArrayBufferLike> to ArrayBuffer:
- Convert a binary NodeJS Buffer to JavaScript ArrayBuffer
A “small” Buffer 's buffer property is an ArrayBuffer that represents the entire memory pool So in this case, the ArrayBuffer and the Buffer varies in size
- How do you implement a circular buffer in C? - Stack Overflow
Do you need a circular buffer or a queue? The required operations make it sound like queue I admit that with the requirement of a fixed size using a circular buffer make sense, but I'm not sure the question title reflects your actual question
