2022-10-04 19:11:54 +02:00

libc: Add strncpy and strncat, and deprecate strcpy and strcat (which, since we're building with -Werror, is an instant ban from using these functions)

Kernel: Do not stop interrupts by default in the interrupt handler
...
I always knew you can choose if interrupts are enabled for a specific ISR in the IDT entry, but at some moment there was a bug and I thought maybe that fixed it. Now reverting that doesn't break anything, so... let's do it :)

Add vprintf, (v)sprintf and (v)snprintf to libc + move the non v-printfs to stdio.cpp, since they can now call their v-variants and thus don't depend on internal_printf
2022-10-03 19:59:33 +02:00

Do not use __builtin_alloca in puts (could overflow the stack for large strings)

Add printf() and puts(), quite primitive, looks like hex printing isn't there yet...
