c - A __attribute__((packed)) like attribute not GCC Specific -

-

i use __attribute__((packed)); make items of struct being stored in memory after critical low-level development.
__attribute__((packed)); gcc specific wonder if there similar solution works on ansi/c89/c99/c11 compilers or @ least of them.

there no standard approach accomplish __attribute__((packed)) does. typical solution use #ifdef's handle different compilers. can find few solutions approach @ so post contains details on visual c++ equivalent of __attribute__((packed)). alternatively, gcc supports windows struct packing pragmas, if concerned windows , gcc use windows approach.

i using enumerator values flags: typedef enum { = 0x00, b = 0x01u, // u has no influence, expected c = 0x02u, // u has no influence, expected ... } enum_name; volatile unsigned char* reg = someaddress; *reg |= b; according misra-c:2004 bitwise operations shall not done signed type. unfortunately, compiler iar use signed int (or short or char) underlying type of enums, , option can find relates size, not signedness ("--enum-is-int"). according iar c/c++ development guide arm , pages 169 , 211, can define type of enum s if enable iar language extensions ( -e command-line option, or project > options > c/c++ compiler > language > allow iar extensions in ide). in particular, should define "sentinel" value, make sure compiler chooses correct type. prefers signed types, , uses smallest possible integer type, sentinel should largest positive integer corresponding unsigned integer type can describe. example, typedef enum
