Hi everyone,
I am tryig to port Linux code to QNX.
Is there a function similar to cpu_to_le32 ( linux) for QNX.?
I found that the le32_to_cpu fn is replaced by ENDIAN_LE32 in QNX.

Thanks In Advance

You should be able to use the same thing (ENDIAN_LE32). Notice
they boil down to the same on linux.

Hi Sean Thanks for a reply…
But this lousy brain still require a bit more info… :slight_smile:)

My code is something like this…
frag[0].length = cpu_to_le32(np->rx_buf_sz | LastFrag);

Here “length” will be used by the NIC in its DMa transfer operation…

Do u think simply an ENDIAN_LE32 will work … !!!

Please clarify
regards
Sarath
