i have alot of data (declar:double), how do i bytes-swap all my data using a function on CVI.

Is there any information or example to share?

Hi Chris,

You can use "endianess" functions...(see attached)

(so I guess that you will need to use "ToOtherEndian64" function)

Thanks for the information,  

just to check with you, Do you know CVI is using big or little endian?

[chris_chua]

hehe im blur, why do you said so( ToOtherEndian64)?, meaing base and above requirement i can only use this( ToOtherEndian64) and not ToBigEndian64 ??? can expain reason?

Thanks

I think that CVI is using little endian.

For "ToOtherEndian64" function, I was just underlining the fact that "double = 64 bits". But depending on your need, you will maybe have the possibility to use "ToBigEndian64" function. 🙂

About CVI endianess, somebody asked the same question and it seems that my answer was not correct (on my computer it is using little endian, that's why I thought it was the same in every system). The good answer is here :
