# `CORE_INTERRUPTABLE_HALT_WHILE(a)` - macro
This halts until **_a_** is true.
Used when working with blocking variables in e.g. thread safe functions.
To avoid deadlocks, this macro won't halt, while the system is handling an interrupt.

# `CORE_HALT_WHILE(a)` - macro
This halts until **_a_** is true.
Used when working with blocking variables in e.g. thread safe functions.

**Warning:** When a function containing this macro is used while handling an interrupt,
this could cause deadlocks, consider using [CORE_INTERRUPTABLE_HALT_WHILE](https://nerdcult.net/projects/noxos/docs/codebase/utils/core.h/#core_interruptable_halt_whilea---macro) instead.

# `CORE_HALT_FOREVER` - macro
This halts forever and warns about this in the log.
