answer:以下是使用这些函数写的代码，实现了两个进程同时操作一块SMR： #include <stdio.h> #include <stdlib.h> #include <fcntl.h> #include <unistd.h> #include <sys/mman.h> #include <sys/stat.h> #include <sys/types.h> #define SMR_FILE "smr.file" // SMR文件名 #define SMR_SIZE 1024 // SMR大小 int main() { int fd, ref_cnt, *ref_ptr; void *smr_ptr; pid_t pid; // 初始化SMR子系统 if(ot_smr_init() < 0) { printf("failed to initialize SMR subsystemn"); return -1; } // 创建SMR文件 fd = open(SMR_FILE, O_RDWR | O_CREAT, 0666); if(fd < 0) { printf("failed to create SMR filen"); return -1; } // 调整SMR文件大小 if(ftruncate(fd, SMR_SIZE) < 0) { printf("failed to truncate SMR filen"); return -1; } // 将SMR文件映射到当前进程的虚拟地址空间中 smr_ptr = ot_smr_mmap(NULL, SMR_SIZE, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); if(smr_ptr == MAP_FAILED) { printf("failed to mmap SMR filen"); return -1; } // 在SMR块中分配一个整数计数器 ref_ptr = (int *)ot_smr_alloc(sizeof(int)); if(ref_ptr == NULL) { printf("failed to allocate ref countern"); return -1; } // 初始化计数器 *ref_ptr = 1; // 将计数器加入SMR块引用计数 ot_smr_add_ref(smr_ptr, (void *)ref_ptr); // 创建子进程 pid = fork(); if(pid < 0) { printf("failed to forkn"); return -1; } else if(pid == 0) { // 子进程 while(1) { // 子进程不断从SMR中读取数据 printf("Child process read SMR data: %sn", (char *)smr_ptr); // 休眠1s sleep(1); } } else { // 父进程 while(1) { // 父进程不断向SMR中写入数据 printf("Parent process write SMR data: Hello SMRn"); sprintf((char *)smr_ptr, "Hello SMR"); // 休眠1s sleep(1); } } // 分离SMR映射 if(ot_smr_munmap(smr_ptr, SMR_SIZE) < 0) { printf("failed to unmap SMR filen"); return -1; } // 减少计数器引用次数 ref_cnt = ot_smr_dec_ref(smr_ptr, (void *)ref_ptr); if(ref_cnt == 0) { // 释放SMR块 ot_smr_free(smr_ptr); } // 关闭SMR文件 if(close(fd) < 0) { printf("failed to close SMR filen"); return -1; } // 删除SMR文件 if(unlink(SMR_FILE) < 0) { printf("failed to delete SMR filen"); return -1; } // 关闭SMR子系统 ot_smr_deinit(); return 0; }
