Typedef Documentation

rpmMemFailFunc

typedef void *(* rpmMemFailFunc) (size_t size, void *data)

Memory allocation failure callback prototype. When registered through rpmSetMemFail(), this gets called if memory allocation through rmalloc() and friends fails. If the application can somehow recover memory here, it can return a newly allocated memory block of requested size, otherwise it must return NULL after performing it's own shutdown deeds or terminate itself.

Parameters

size	Size of allocation request in bytes
data	User data (or NULL)

Returns

Allocated memory block of requested size or NULL

Function Documentation

rpmSetMemFail()

rpmMemFailFunc rpmSetMemFail	(	rpmMemFailFunc	func,
		void *	data
	)

Set memory allocation failure callback.

Parameters

func	Allocation failure callback function
data	User data (or NULL)

Returns

Previous callback function
