Detailed Description

Memory allocation related helpers.

Typedef Documentation

typedef void(* sb_free_func_t) (void *ptr)

Function signature for helpers that are used to free memory of custom types.

Each function should receive the pointer, and free the memory used by the type as needed.

The sb_slist_free_full function is an example of usage of these helper functions.

Parameters

ptr	An dinamically allocated pointer to be free'd.

Function Documentation

void* sb_malloc

(

size_t

size

)

Safe malloc replacement function. This function validates the output of the libc's malloc call and aborts if needed. See malloc(3) for details.

Parameters

size	Number of bytes to be allocated.

Returns

A pointer to the allocated memory.

Examples:

hello_custom_error_type.c.

void* sb_realloc	(	void *	ptr,
		size_t	size
	)

Safe realloc replacement function. This function validates the output of the libc's realloc call and aborts if needed. See realloc(3) for details.

Parameters

ptr	A pointer to be resized.
size	New number of bytes allocated after reallocation.

Returns

A pointer to the reallocated memory.
