◆ ft_msleep()

void ft_msleep ( int ms )

Sleep for approximately ms millisecondes using a little trick.

Sets VMIN = 0 so read() doesn't wait for a character
Sets VTIME = ms / 100 so read() blocks for that many deciseconds before returning with nothing
The result is thus an imitation of a sleep that doesn't use usleep() which is not allowed by the Minishell subject
Original terminal settings are saved and restored after the read

Parameters

ms	Milliseconds to sleep

Warning: Because of VTIME resolution, precision is limited to ~100 ms
