Function Documentation

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
