write_str

Your mission

Implement a function that outputs every character of a null-terminated string to file descriptor 1.

See it in action

write_str("segfault on line one")

Expected result

segfault on line one

Your checklist

For your own tracking. Tests grade your code.

The function receives a pointer to the first character of a null-terminated string.
Use the write syscall to emit each character one at a time until the null terminator is reached.
Do not print the null terminator itself and do not add any extra characters.
