in thread What difference between malloc and Newx, how attach a C string to SV directly?

Note how Perl considers the buffer to belong to Perl now.

yeah, if buf produced from malloc which means it's not belong to perl, program will throw a segment fault error. I guess Newx maybe not just a simple wrap of malloc, it does a register pointer address to perl when which assure perl could free it safely.

I think there is a way to have a PV be a pointer to memory that is not free'd by Perl, but...

yes, I think it too, that's why I post question on perlmonks. ;)




I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
