Macro Definition Documentation

#define AEArgumentScalar

(

argument

)

(AEArgument){ YES, &(typeof(argument)){argument}, sizeof(argument) }

Create a scalar argument for use with AEMessageQueuePerformSelectorOnMainThread.

For example, to create a literal int argument:

AEArgumentScalar(1);

To create a pointer argument:

__unsafe_unretained MyClass * myPointer;
AEArgumentScalar(myPointer);

To create a literal structure argument, use AEArgumentStruct; to create an argument that points a memory region, use AEArgumentData.

Parameters

argument

The argument value

Returns

The initialized argument

#define AEArgumentStruct

(

argument

)

(AEArgument){ YES, &(argument), sizeof(argument) }

Create a structure argument for use with AEMessageQueuePerformSelectorOnMainThread.

For example (note extra parentheses around braced structure initialization):

AEArgumentStruct(((struct MyStruct) { value1, value2 }))

or

struct myStruct value = { value1, value2 };
AEArgumentStruct(value)

Parameters

argument

The struct argument

Returns

The initialized argument

#define AEArgumentData	(		buffer,
			size
	)		(AEArgument) { NO, buffer, size }

Create a data argument for use with AEMessageQueuePerformSelectorOnMainThread.

The memory region indicated will be copied. For example:

void * myBuffer = ...;
AEArgumentData(myBuffer, myBufferLength);

Parameters

buffer	Pointer to the buffer to copy
size	Number of bytes to copy

Returns

The initialized argument

Typedef Documentation

typedef void(^ AEMessageQueueBlock)()

Block.

Variable Documentation

AEArgument AEArgumentNone

Empty argument, to terminate list of arguments in AEMessageQueuePerformSelectorOnMainThread.
