Log Levels

typedef enum fq_log_level_t {
    FQ_LOG_NONE   = 0,
    FQ_LOG_ERROR  = 1,
    FQ_LOG_WARN   = 2,
    FQ_LOG_INFO   = 3,
    FQ_LOG_DEBUG  = 4
} fq_log_level_t;

Log Callback

typedef void (*fq_log_fn)(fq_log_level_t level, const char *message, void *ctx);

Example

void my_logger(fq_log_level_t level, const char *msg, void *ctx)
{
    printf("[%d] %s\n", level, msg);
}

fq_scheduler_config_t cfg;
fq_scheduler_config_default(&cfg);
cfg.log_callback = my_logger;
cfg.log_level    = FQ_LOG_DEBUG;
cfg.log_context  = NULL;
