i use keil arm rvct and have small problem RVCT have no #pragma pack(1) but when i got program from my friend i didnt see this program and RVCT didnt say warning about this command - and i have problem because this command destroy execute program for example
#pragma pack(1)
typedef struct { unsigned char command; unsigned long packets; unsigned char reserved[3];
} COMMAND2;
int main() { COMMAND2 cmd2; unsigned long Size;
cmd2.command = 0x01; cmd2.packets = 1000; Size = cmd2.packets; Size = cmd2.command; }
when run this program Size <> 1 at the end !!!
undetermine command #pragma pack(1) create error and compiler dont say warning about this command if correct program for RVTC
typedef __packed struct { unsigned char command; unsigned long packets; unsigned char reserved[3];
we will get ok result
