sigaltstack: function not implemented

Hi all,

 

when I make a call to sigaltstack, the call returned with errno set to ENOSYS.

Why is this so?

I used the Petalinux 2013.10 toolchain and am running a 3.6 kernel.


Regards,

Whye Hoong

Re: sigaltstack: function not implemented

i can confirm sigaltstack() is still unimplemented in Petalinux-2016.1 or 2018.1 or 2018.3. Needed it to solve a segmentation fault issue.

Any help?
