Fun to see the Linux kernel follow in #curl's footsteps! (we removed the last strncpy from curl in late 2025)

@bagder Long time ago, there was small project called qmail in C, author started project by rethinging/replacing almost every standard C function.

@bagder so some time around 2040 we'll have 99% of things using a kernel without it.

My snark comes from two months of broken audio stack on my android phone that was a unterminated string issue.

Do I understand correctly that the problem with strncpy is that after the call you don't know if the buffer is NUL terminated or not?

[bagder@mastodon.social]

@kasperd yes. but we also find that code generally improves using other solutions so in curl we don't replace it with something that guarantees a null terminator. We write the code another way instead.
