Stack Memory Management

It is less commonly used, but possible, to dynamically allocate stack memory. Functions include:

  • alloca — the main stack memory allocation function (<alloca.h>.
  • _malloca — stack memory allocation (Microsoft CRT)
  • _freea — free memory on the stack or heap (Microsoft CRT)
  • __builtin_alloca_with_align (GCC version with alignment)

Note that “de-allocation” of a stack block is technically not required, because the memory is reclaimed when the function returns and the stack is unwound.
