How to get the amount of used memory when an application is executed

I have looked through GDB documentation, but haven't found anything that works or shows what I need: the maximum amount of memory that is used by my application.

I'm using MinGW-w64 (GCC for Windows) if that's relevant. I'd like something programmatically, not "look in your task manager". Also: my application executes in one go, it doesn't stop or halt anywhere, and I'd like to keep it that way.

Thanks!

The standard doesn't specify anything deeper than malloc() and free(), which leaves C libraries free to implement them to work in their target environments. The result is that a debugger like GDB that isn't tied to a specific environment will have no insight into memory allocation.

Windows provides functions to return how much memory is being used.

You could wrap malloc/free or new/delete: How-to-profile-memory-usage-of-a-c-program

Thereby you can check how much memory (heap) you are using at any time.
