Using std::vector
In multithreaded environments, protecting concurrent data access is crucial. One approach is to employ std::vector
To address this, consider the following solutions:
1. Leverage std::unique_ptr
Define a unique pointer to std::mutex to manage individual mutexes. However, this approach involves dynamic memory allocation and deallocation for each mutex, leading to performance concerns.
2. Employ std::deque or std::list:
These containers do not impose the same requirements on values as std::vector. Construct mutexes in place or use emplace() or resize() to achieve the desired functionality. Functions like insert() and push_back() are incompatible with this approach.
3. Create an indirection layer with unique_ptr:
Store unique_ptr in a vector. This technique introduces an additional layer of indirection and may be less desirable due to dynamic allocation overhead.
4. Use std::unique_ptr
Allocate an array of mutexes with a fixed size. If more mutexes are required, resize the array dynamically. This provides a flexible solution with less allocation overhead than individual unique pointers.
Based on your requirements, the most appropriate approach is std::unique_ptr
