Detailed Description
Event queue structure for producer/consumer patterns.
Thread-safe queue that supports multiple producers and consumers. Producers can always add items (with overflow handling), while consumers can wait for items or peek before acquiring them.
- Examples:
- examples/runtime/gpio/main.c, and examples/runtime/infrared/main.c.
The documentation for this struct was generated from the following file:
