Detailed Description

A scoped mutual-exclusion guard wrapping a SpinGuardState with RAII semantics.

Constructor & Destructor Documentation

ScopedSpinGuard()

crashpad::ScopedSpinGuard::ScopedSpinGuard ( SpinGuardState & locked_state )

inline

A ScopedSpinGuard wrapping a locked SpinGuardState.

Parameters

[in,out]

locked_state

A locked SpinGuardState. This method holds a pointer to state, so state must outlive the lifetime of this object.

Member Function Documentation

TryCreateScopedSpinGuard()

static std::optional< ScopedSpinGuard > crashpad::ScopedSpinGuard::TryCreateScopedSpinGuard ( uint64_t timeout_nanos, SpinGuardState & state )

inlinestatic

Spins up to timeout_nanos nanoseconds trying to lock state.

Parameters

[in]	timeout_nanos	The timeout in nanoseconds after which this gives up trying to lock the spinlock and returns std::nullopt.
[in,out]	state	The spinlock state to attempt to lock. This method holds a pointer to state, so state must outlive the lifetime of this object.

Returns

The locked ScopedSpinGuard on success, or std::nullopt on timeout.
