Type Parameters

Name	Description
TDelegate	The type of the delegate representing the signature of the target function that this pointer points to.

Remarks

NullablePersistentFunctionPointer<TDelegate> has the following characteristics:

• null-ableYou must check whether the function pointer is null using TryGetNonNull(out PersistentFunctionPointer<TDelegate>) before invoking the function pointer's target function.
• PersistentThe function pointer's target function outlives the pointer's initial scope. You can let the function pointer escape the current scope and store it for later invocation. No guarantees are made about how long the target function will remain valid.
• TypedThe function pointer points to a target function whose signature is represented by TDelegate.

Properties

Name	Description
AsIntPtr	Gets an nint that represents the same memory address as the current pointer.
AsUIntPtr	Gets an nuint that represents the same memory address as the current pointer.
HasTargetFunction	Gets a value indicating whether the current function pointer is non-null.
Null	Gets a NullablePersistentFunctionPointer<TDelegate> that represents a null pointer.
