async_context_poll provides an implementation of async_context that is intended for use with a simple polling loop on one core. It is not thread safe.
The async_context_poll method must be called periodically to handle asynchronous work that may now be pending. async_context_wait_for_work_until() may be used to block a polling loop until there is work to do, and prevent tight spinning.
| typedef struct async_context_poll async_context_poll_t |
Async context type for a simple single-core polling loop.
Holds the state for an async_context_poll instance, which processes asynchronous work by polling rather than using interrupts or threads.
| bool async_context_poll_init_with_defaults | ( | async_context_poll_t * | self | ) |
Initialize an async_context_poll instance with default values.
If this method succeeds (returns true), then the async_context is available for use and can be de-initialized by calling async_context_deinit().
