§ _cbor_alloc_multiple()

void* _cbor_alloc_multiple ( size_t  item_size,
size_t  item_count 
)

Overflow-proof contiguous array allocation.

Parameters
item_size
item_count
Returns
Region of item_size * item_count bytes, or NULL if the total size overflows size_t or the underlying allocator failed

Definition at line 30 of file memory_utils.c.

§ _cbor_realloc_multiple()

void* _cbor_realloc_multiple ( void *  pointer,
size_t  item_size,
size_t  item_count 
)

Overflow-proof contiguous array reallocation.

This implements the OpenBSD reallocarray functionality.

Parameters
pointer
item_size
item_count
Returns
Realloc'd of item_size * item_count bytes, or NULL if the total size overflows size_t or the underlying allocator failed

Definition at line 39 of file memory_utils.c.

§ _cbor_safe_to_multiply()

bool _cbor_safe_to_multiply ( size_t  a,
size_t  b 
)

Can a and b be multiplied without overflowing size_t?
