I have the following definitions....
#import <strings.h>
u_char pkt[95];
u_long a_long;
bzero(&pkt, 95);
a_long = 23L;
bcopy(&a_long, &pkt[UID] 4); <---- This fails to compile...
I get: error - parse error before numeric constant?
What in tarnation does THIS mean... how can I copy the contents of a
local
variable like "a_long" into a specific byte cell in the 'pkt' array of
"u_char"
I have to do an insane convoluted way of dealing with odd-sized packet
fields, and when I define it as a struct, the expected struct size
should be
95 bytes in length, but instead it is 100 bytes in length. WTF?
Ok, so time for plan B... I'm just going to use a character array of
8 bit bytes, and MOVE the variables into the proper offset.... I know
it's a serious kludge, but I got no other choice,
Of course I did the
#pragma option align=packed
Ran some tests, and (sigh), I just cannot start on an odd-byte
boundary for
a field.... is there any other way?
Also tried:
#pragma pack(1)
But (sigh) that don't work either.... is there ANY hope?
John
