Functions
void	write_char_safely (int fd, char c, t_pf *pf)
	Safely writes a single character to a file descriptor.
void	write_safely (int fd, char *str, t_pf *pf)
	Safely writes a null-terminated string to a file descriptor.
void	write_safely_len (int fd, char *str, size_t len, t_pf *pf)
	Safely writes len bytes from a string to a file descriptor.

Detailed Description

Safe low-level write utilities for ft_printf.

This file implements safe wrappers around the write system call used by ft_printf. It ensures that:

• All bytes are written even if the syscall is interrupted
• Errors are tracked through the t_pf structure
• Output progress (total) is updated reliably

These utilities are essential for robust and portable output handling when implementing a printf-like function.
