#include <qb/qblog.h>

int32_t qb_log_filter_ctl(
    int32_t                  value,
    enum qb_log_filter_conf  c,
    enum qb_log_filter_type  type,
    const char              *text,
    uint8_t                  low_priority
);

she takes five arguments and she is not sorry about it 💅

🎀 DESCRIPTION 🎀

so bestie, here's the tea: this function is your remote control for the tags and targets fields on a callsite — and you get to flip those switches at runtime, no recompile, no restart, no drama. iconic behavior, honestly.

🧚 STRUCTURES 🧚

first up, the c argument vibes — this is the enum qb_log_filter_conf, and every single one of these is here:

enum qb_log_filter_conf {
      QB_LOG_FILTER_ADD;
      QB_LOG_FILTER_REMOVE;
      QB_LOG_FILTER_CLEAR_ALL;
      QB_LOG_TAG_SET;
      QB_LOG_TAG_CLEAR;
      QB_LOG_TAG_CLEAR_ALL;
};

and then the type argument — this is enum qb_log_filter_type, the whole squad, no one left behind:

enum qb_log_filter_type {
      QB_LOG_FILTER_FILE;
      QB_LOG_FILTER_FUNCTION;
      QB_LOG_FILTER_FORMAT;
      QB_LOG_FILTER_FILE_REGEX;
      QB_LOG_FILTER_FUNCTION_REGEX;
      QB_LOG_FILTER_FORMAT_REGEX;
};

look at all those options. she ate. 🔥
