avahi_strdup
char * avahi_strdup(const char *s)
Just like libc&#39;s strdup()
avahi_strndup
char * avahi_strndup(const char *s, size_t l)
Just like libc&#39;s strndup()
avahi_memdup
void * avahi_memdup(const void *s, size_t l) AVAHI_GCC_ALLOC_SIZE(2)
Duplicate the given memory block into a new one allocated with avahi_malloc()
AvahiAllocator::free
void(* free)(void *p)
Definition: malloc.h:77
avahi_malloc
void * avahi_malloc(size_t size) AVAHI_GCC_ALLOC_SIZE(1)
Allocate some memory, just like the libc malloc()
AvahiAllocator
struct AvahiAllocator AvahiAllocator
Wraps allocator functions.
avahi_strdup_printf
char * avahi_strdup_printf(const char *fmt,...) AVAHI_GCC_PRINTF_ATTR12
Like sprintf() but store the result in a freshly allocated buffer.
avahi_free
void avahi_free(void *p)
Free some memory.
avahi_realloc
void * avahi_realloc(void *p, size_t size) AVAHI_GCC_ALLOC_SIZE(2)
Similar to libc&#39;s realloc()
k
static void size_t k
Definition: malloc.h:48
avahi_malloc0
void * avahi_malloc0(size_t size) AVAHI_GCC_ALLOC_SIZE(1)
Similar to avahi_malloc() but set the memory to zero.
AvahiAllocator
Wraps allocator functions.
Definition: malloc.h:75
avahi_set_allocator
void avahi_set_allocator(const AvahiAllocator *a)
Change the allocator.
