Kuidas määrata süsteemis lubatud maksimaalne puffermaht?

In Go, the maximum allowable buffer size depends on the specific buffer type and system limitations (RAM, OS restrictions). For example, for a buffer in bytes.Buffer or a byte slice, memory can be allocated up to the available size.

To determine the maximum permissible buffer size:

• You can experiment by allocating buffers of increasing size and catching memory allocation errors.
• For network buffers (e.g., in bufio.Reader), the maximum size depends on OS settings and restrictions.
• In some cases, system limits can be checked using ulimit or similar tools.

Example of creating a buffer with a size limited by memory:

buf := make([]byte, maxSize) // maxSize — size that does not exceed available memory

Overall, in Go, there is no strict limit on buffer size other than available memory and OS restrictions.
