C++ :: Variable Inside A Class - How To Manage Memory Allocation

recently I developed a class header only in C++ to deal with byte arrays. Since I developed programs in other languages that had some libraries to dial with byte arrays, I developed one that the syntax is very similar to other languages.

Since I'm not very familiar with memory management, I was concerned about somethings I've read about (ex: memory fragmentation).

Here is a very simple example of my practice:

class ByteArray {
public:
ByteArray(size_t size) {
buffer = (int8_t*)malloc(size);
}

[Code].....

The class is intended to be used as part of comunication protocol in a webserver, byte arrays are created and destroyed a lot. Should I use pools? Is there a better practice? Am I doing everything wrong (laugh)?
