Function Documentation

context_entry()

void context_entry ( zth::Context *  context )

noexcept

Entry point of the fiber.

This function is called by the actual context switching mechanism. It will call the entry function, as specified by the Context's attributes during creation, which is zth::Fiber::fiberEntry() by default.

This function does not return. When the entry function returns, the context is considered dead, the Worker's scheduler is invoked, and the context is destroyed.
