littel to big endian question...

[Tuxedo]

HI ALL!
I'm working on a routine to convert littel to big endian longwords and get some problem...
maybe I'm only a newbe guy...
To convert shorts was all really simple! I use a ror(or rol) and all works great
The poblem was when I try to convert longs...probably I miss some function but I cant reach to swap the position for bytes to convert from little to big...
Any idea here?
I know that i have to swap the bytes of a long(for ex: 1,2,3,4 to 4,3,2,1) but I cant found any function in hollywood to do that...

Thanks a LOT!!!!!!

Solved
Simply copied a C method since the bitwise opertors was the same in Hollywood too
ANd I've miss the bitwise operators of Hollywood since today...

So topic closed

Would be cool if you would share the solution you found in case someone else also gets in trouble on this topic.

Thanks!

Well...
I find rather easly the code:

inline void endian_swap(unsigned short& x)
{
x = (x>>8) |
(x<<8);
}

inline void endian_swap(unsigned int& x)
{
x = (x>>24) |
((x<<8) & 0x00FF0000) |
((x>>8) & 0x0000FF00) |
(x<<24);
}

On the net...
Than sonce the logical commands was exactly the same in Hollywood too I simply adapted that to my code
Easy
