LWIP_MEM_ALIGN_BUFFER macro

Calculate safe memory size for an aligned buffer when using an unaligned type as storage. This includes a safety-margin on (MEM_ALIGNMENT - 1) at the start (e.g. if buffer is u8_t[] and actual data will be u32_t*)

Syntax

from arch.h:287

#define LWIP_MEM_ALIGN_BUFFER(size) (((size) + MEM_ALIGNMENT - 1U))

Arguments

size
