Hi,

Can you explain your temporary_memory struct?

Answered by bagaffey

Yeah, this is used to make fast temporary memory allocations.
The temporary_memory struct has 3 properties:

A pointer to a memory_arena
A pointer to a memory block (defined by the platform)
Used space

This thing is meant to be used in this way:

Make a temporary allocation
Do some work
Roll the arena base back when done (this frees the memory super fast).
