Function Documentation

int uriCompleteMemoryManager	(	UriMemoryManager *	memory,
		UriMemoryManager *	backend
	)

Wraps a memory manager backend that only provides malloc and free to make a complete memory manager ready to be used.

The core feature of this wrapper is that you don't need to implement realloc if you don't want to. The wrapped memory manager uses backend->malloc, memcpy, and backend->free and soieof(size_t) extra bytes per allocation to emulate fallback realloc for you.

memory->calloc is uriEmulateCalloc. memory->free uses backend->free and handles the size header. memory->malloc uses backend->malloc and adds a size header. memory->realloc uses memory->malloc, memcpy, and memory->free and reads the size header. memory->reallocarray is uriEmulateReallocarray.

The internal workings behind memory->free, memory->malloc, and memory->realloc may change so the functions exposed by these function pointer sshould be consided internal and not public API.

Parameters

memory	OUT: Where to write the wrapped memory manager to
backend	IN: Memory manager to use as a backend

Returns

Error code or 0 on success

void* uriEmulateCalloc	(	UriMemoryManager *	memory,
		size_t	nmemb,
		size_t	size
	)

Offers emulation of calloc(3) based on memory->malloc and memset. See "man 3 calloc" as well.

Parameters

memory	IN: Memory manager to use, should not be NULL
nmemb	IN: Number of elements to allocate
size	IN: Size in bytes per element

Returns

Pointer to allocated memory or NULL

void* uriEmulateReallocarray	(	UriMemoryManager *	memory,
		void *	ptr,
		size_t	nmemb,
		size_t	size
	)

Offers emulation of reallocarray(3) based on memory->realloc. See "man 3 reallocarray" as well.

Parameters

memory	IN: Memory manager to use, should not be NULL
ptr	IN: Pointer allocated using memory->malloc/... or NULL
nmemb	IN: Number of elements to allocate
size	IN: Size in bytes per element

Returns

Pointer to allocated memory or NULL

int uriTestMemoryManager

(

UriMemoryManager *

memory

)

Run multiple tests against a given memory manager. For example, one test

1. allocates a small amount of memory,
2. writes some magic bytes to it,
3. reallocates it,
4. checks that previous values are still present,
5. and frees that memory.

It is recommended to compile with AddressSanitizer enabled to take full advantage of uriTestMemoryManager.

Parameters

memory

IN: Memory manager to use, should not be NULL

Returns

Error code or 0 on success
