问如何将特定线程的stdout输出重定向到/dev/null？

#include <stdio.h>
#include <pthreads.h>

struct Logger
{
    pthread_t blockedThreads[256];
    int qty;
};

struct Logger *createLogger()
{
    struct Logger *logger = (Logger *)malloc(sizeof(Logger));
    logger->qty = 0;
    return logger;
}

void blockThread(struct Logger *logger, pthread_t thread)
{
    for (int i = 0; i < logger->qty; ++i) {
        if (logger->blockedThread[i] == thread {
            return;
        }
    }

    logger->blockedThreads[logger->qty] = thread;
    logger->qty++;
}

void log(struct Logger *logger, const char *message)
{
    for (int i = 0; i < logger->qty; ++i) {
        if (logger->blockedThread[i] == pthread_self()) {
            return;
        }
    }

    // DO REAL LOGGING HERE
}
