Detailed Description

A structure holding internal state for a pending synchronous operation on a work item or queue.

Instances of this type are provided by the caller for invocation of k_work_flush(), k_work_cancel_sync() and sibling flush and cancel APIs. A referenced object must persist until the call returns, and be accessible from both the caller thread and the work queue thread.

Note

If CONFIG_KERNEL_COHERENCE is enabled the object must be allocated in coherent memory; see arch_mem_coherent(). The stack on these architectures is generally not coherent. be stack-allocated. Violations are detected by runtime assertion.
