Function Documentation

cyaml_mem()

void * cyaml_mem	(	void *	ctx,
		void *	ptr,
		size_t	size )

CYAML default memory allocation / freeing function.

This is used when clients don't supply their own. It is exposed to enable clients to use the same allocator as libcyaml used internally to allocate/free memory when they have not provided their own allocation function.

Parameters

[in]	ctx	Allocation context, unused.
[in]	ptr	Existing allocation to resize, or NULL.
[in]	size	The new size for the allocation.

Note

When size == 0 this frees ptr.

Returns

If size == 0, returns NULL. If size > 0, returns NULL on failure, and any existing allocation is left untouched, or return non-NULL as the new allocation on success, and the original pointer becomes invalid.
