qt_team_critical_section(3)

✨ NAME ✨

qt_team_critical_section — bestie, this one marks a region of code that must not be interrupted by a eureka 💖 (yes really, that's the whole job, and it's lowkey iconic)

🎀 SYNOPSIS 🎀

#include <qthread.h>

void
qt_team_critical_section (qt_team_critical_section_t boundary);

🦋 DESCRIPTION 🦋

okay so. this function exists to mark a region of code that must not be interrupted by a eureka. that's the vibe. that's the assignment. 💅

why do you need it? two main reasons, and they're both giving "please don't interrupt me mid-sentence":

1. it lets you do small operations that just do not work well when they get interrupted — think printf() — inside eureka-able code, no cap.
2. it lets you correctly manipulate shared data structures that require locking. 🫶

here's the part that actually matters, so listen up bestie: if a eureka moment gets reached by another thread while the current thread is chillin' inside a critical section, the effect will be as if the current thread was able to complete its critical section just before the eureka moment was reached. like, the timeline gets rearranged so it looks clean. main character energy fr fr ✨

the argument, boundary, can be one of exactly two values:

• BEGIN — you're at the beginning of a critical section 🌸
• END — you're at the end of one 🎀

and the iconic part? critical sections CAN be nested, if necessary. go off, stack them, she contains multitudes. 👑

heads up: boundary has to be one of those two values. there is no third option. don't get creative, babe. 🙈
