有没有办法在c中运行任何exec系列函数作为线程

#include<stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>

void *exec_thread(void *arg) {
    char *cmd = (char *)arg;
    execl(cmd, cmd, NULL);
    perror("execl");
    exit(EXIT_FAILURE);
}

int main(int argc, char *argv[]) {
    if (argc != 2) {
        fprintf(stderr, "Usage: %s <executable>\n", argv[0]);
        exit(EXIT_FAILURE);
    }

    pthread_t thread;
    if (pthread_create(&thread, NULL, exec_thread, argv[1]) != 0) {
        perror("pthread_create");
        exit(EXIT_FAILURE);
    }

    pthread_join(thread, NULL);
    return 0;
}
